Mumbai, July 25 - Four activists said to belong to Raj Thackeray's Maharashtra Navnirman Sena (MNS) were arrested here Saturday on charges of gang raping a minor girl working as a maid servant, police said.

The four -- Ganesh Gatkar, Ganesh Kale, Narendra Salunkhe and Umesh Borade -- were produced before a magistrate in Andheri court this afternoon and remanded to police custody till July 28, according to senior police inspector of MIDC police station Pradeep Suryawanshi.

He said that the incident occurred last Sunday around 2 p.m., when the accused kidnapped the girl while she was going home.

They took her to a municipal garden in the neighbourhood and allegedly raped her in the cabin of the security guards there.

The injured victim was allowed to go but not before she was threatened with dire consequences if she opened her mouth.

Suryawanshi said that the victim finally took courage Friday and revealed the incident to her mother, who also works as a maid in the same locality. She brought her daughter to the police station and a complaint was lodged following which the accused were rounded up.

The incident comes barely one month after Bollywood actor Shiney Ahuja was arrested for allegedly raping his domestic help in Andheri West.
