The district administration deployed additional forces in the Kharkhauda area on Monday to diffuse communal tension after a 20-year-old woman complained of forced conversion at a madrasa and subsequent gang-rape.
Meerut superintendent of police (rural) MM Beg confirmed arrest of three out of four accused named in the complaint, including a woman and a girl.
He said raids are on to nab the Urdu teacher of the madrasa.
The alleged forced conversion took place at a madrasa in Dautai village of neighbouring Hapur on July 30, a day after Eid.
The woman worked as a teacher in the madrasa at Sarawa village, 40 km from Dautai and around 25 km from Meerut.
The incident in the communally sensitive belt in western Uttar Pradesh took place days after clashes between two communities left three persons dead and several injured at Saharanpur, around 120 km from Meerut.
Last year's communal flashpoint Muzaffarnagar is just 45 km from Meerut.
Tension flared up in the district on Sunday when hundreds of angry protesters took to the streets in Kharkhauda after police registered a case over the alleged forced conversion.
The police officer said that additional security forces including jawans of Rapid Action Force (RAF) and Provincial Arms Constabulary (PAC) have been deployed in the area to maintain law and order.
Due to ill health, police could not produce the victim in a city court where her statement was to be recorded on Monday. It will be done on Tuesday.
He said that girl's medical examination has been concluded but added she would have to undergo a few additional tests.
The Hindu teacher, who taught Hindi and English at the madrasa, had alleged that after her conversion, she was taken to Muzaffarnagar where she was kept in confinement.

She also alleged that she was gang-raped during her confinement. She, however, did not identify the rapists.
She claimed to have escaped from the clutches of her abductors and return to her house in Kharkhauda and narrate the ordeal to her family-members.
The girl's family had lodged a missing complaint at Kharkhauda police station on July 30.
On Monday, the Muzaffarnagar district administration also raided a religious education centre but found no girl being held captive there.
The raid was carried out after the victim claimed that 20 more girls were held captive at the place in Muzaffarnagar.
District magistrate Kaushal Raj Sharma said that the primary school had 258 girls registered as students but most of them had gone home for a festival.
The institute has classes from one to five.
