The Delhi Police on Tuesday arrested a 67-year-old madrassa teacher from North West Delhi’s Narela area for allegedly raping a nine-year-old girl. The girl is being treated at the Baba Saheb Ambedkar Hospital.

The police have registered a case against the teacher, Zakir Alam, under sections of the Protection of Children against Sexual Offences Act and the Indian Penal Code, Deputy Commissioner of Police Rajneesh Gupta told the Hindustan Times. Gupta added that they were verifying if Alam raped the girl in the madrassa’s premises.

Alam had allegedly raped her on February 25. The girl’s parents told the police that Alam had threatened her with dire consequences if she told anyone about the rape, The Hindu reported. On February 26, the girl lost consciousness and was taken to a hospital. When the doctors told the parents that she had been sexually assaulted, she told her mother about the incident, after which a complaint was filed.

Alam is an Arabic language teacher who has been at the madrassa for several years, the police said.

Delhi Commission for Women Chairperson Swati Maliwal said on Twitter that the crime sickened her, and said both the system and society were responsible for such incidents.
