A 39-year-old man has been arrested for allegedly raping his 65-year-old mother twice, claiming to be punishing her for an alleged relationship she had in the past, media reports said.

According to police, the woman, accompanied by her 25-year-old daughter, filed the FIR, reported NDTV.

The assaults took place shortly after the family returned from a religious trip to Saudi Arabia.

The woman lives with her husband, a retired government employee, her accused son, and her younger daughter in Delhi's Hauz Qazi area.

The family also has an elder daughter who is married and lives nearby with her in-laws.

On July 17, the woman, her husband, and her younger daughter travelled to Saudi Arabia.

During their trip, the accused called his father and insisted he return to Delhi immediately.

He also asked his father to divorce his mother, accusing her of having illicit relationships during his childhood.

The complaint stated that after the family returned to Delhi on August 1, the accused locked his mother in a room, forced her to remove her burqa, and beat her. He allegedly told her she had "spoiled" him in childhood.

The woman left home and took shelter at her elder daughter's residence.

She returned on August 11, but the abuse continued. At around 9:30 pm, the accused told his family he wanted to speak with his mother in private.

He again locked her in a room, raped her, and stated he was punishing her for her "past relationships."

On August 14, at around 3:30 am, the accused raped her a second time.

The next day, the woman confided in her younger daughter, who encouraged her to approach the police.

The two went to Hauz Qazi police station and submitted a written complaint.
