In a shocking incident, a mentally challenged woman was raped by a ward boy and a security guard in the lift of a Municipal Hospital at Bhosari near Pune, police said on Monday. Both the accused have been arrested.

The 30-year-old woman, who is also speech impaired, had been admitted to the hospital from a shelter home where she lived, following health complaints on August 26, 2013. The accused allegedly took the woman to the lift on the pretext of shifting her to another ward and raped her three days later, police said.

After being discharged from the hospital on August 31, the woman returned to the shelter home where she informed about the crime to the caretaker through sign language.

Following this, a case was filed leading to the arrests, police added.
