New Delhi (CNN) - The headmistress of the Indian school that authorities say served toxic lunches, killing 23 students, was arrested Wednesday, police said.
Meena Kumari, 36, was taken into custody on her way to a court where she had gone to surrender herself, police Superintendent Sujeet Kumar told CNN. She will be questioned Wednesday and taken before the court Thursday, he said.
Authorities had been working to track down Kumari, who had been at large since the July 16 incident.
The whereabouts of her husband, who is not named as an accused person in the case, are still not known, Kumar added. Police want to question him in connection with the case.

Partna, India (CNN) - A week after an Indian school served toxic food to students, leaving 23 dead, its headmistress remains missing along with her husband, police said Tuesday. A nine-member team of officers has been formed to investigate and track down the principal, Meena Kumari, police superintendent Sujeet Kumar said.
Police presence is heavy in the village in Bihar state, especially around the principal's home.
Authorities have recorded statements from 40 witnesses, including child survivors of the July 16 food poisoning, Kumar said.
Residents went on a rampage a day after the toxic meals were served in the local government school, torching at least four police cars.
In acts of protest, parents of at least three children have buried their kids near the school - one right in front of the building, according to officials.
Police will ensure the headmistress' safety when she resurfaces or is taken into custody for questioning, authorities said.

Patna, India (CNN) - Pesticides have been found in the food and oil used in a free school lunch that killed 23 students and sickened 25 others on Tuesday in northern India's Bihar state, police said Saturday.
Forensic scientists found monocrotophos, an organophosphorus compound used as an insecticide, "in the samples of oil from the container, food remains on the platter and mixture of rice with vegetables in an aluminum utensil," Assistant Director General Ravinder Kumar told reporters in Patna.
Monocrotophos, which is used for agricultural purposes, is toxic to humans.
An administrative inquiry has pointed to negligence by the school headmistress in supervising food preparation for the children, Bihar state's midday meal director R. Lakshamanan told CNN on Friday.
The cook, Manju Devi, was hospitalized after eating the food she prepared, doctors said.
Devi told police that the headmistress, Meena Kumari, did not heed her warning that the mustard oil used to prepare Tuesday's lunch looked and smelled bad and instead insisted that she continue preparing the meal, Lakshmanan said, citing the inquiry report.
Police told CNN that investigators were trying to find Kumari to question her.
The investigation found compromised hygiene and sanitation in the school, which was running from a single-room makeshift building, he added.

Bihar, India (CNN) - A father holds his limp child in his arms, carrying her from the school he trusted to take care of her. A video camera focuses on his face locked in total anguish. Everyone around him is shouting. He goes to the back of an open van and struggles to keep the white blanket he's wrapped around his child's body from slipping as he lays the body down.The mother of a 5-year-old repeatedly calls her daughter's name.
Why aren't you coming back, she pleads.
"Why isn't anyone bringing Dipu back?!"
These moments came in the wake of the deaths of 23 Indian children who were poisoned by school lunches they were given Tuesday, authorities say.
The students, who authorities said were between the ages of 5 and 12, started vomiting soon after their first bite of rice and potatoes at their government primary school in the northern state of Bihar. Some fainted.
Earlier, authorities had said 22 children had died, but on Thursday district magistrate Abhijit Sinha explained that one deceased boy had not been counted in the initial death toll because his father had taken his body without handing it over for autopsy.
Grief and anger so permeate this poverty-stricken community that parents of at least three children have buried their lost ones near the school - one right in front of the building, according to CNN journalists who saw the burial mounds. Sinha told CNN that the burials were acts of protest.
Demonstrations have popped up around the area as people seek answers about how this tragedy could have happened. One video segment showed men apparently attacking a school bus with sticks. Others gathered and held signs.
Students at nearby schools refused to eat.
"I am scared now. ... There is fear in our hearts," one child told CNN sister network CNN-IBN.
Meanwhile, a top federal official said authorities had warned of safety problems with the state's school meal program months ago.
And police told CNN that investigators have been unable to find the headmistress of the school in order to question her.
Authorities have not named the headmistress and her husband, whom they also want to interview, local police chief Sujit Kumar said Thursday.
