The woman, identified only as Swati, had befriended the 55-year-old bank officer some months ago, said Dilip Soni, Additional Superintendent of Police (Crime Branch), today.
Later, she introduced him to another girl. Some days ago, Swati took the officer to a rented place in Bhanwarkuna area, where he was shot by a spy camera, allegedly in a compromising position with the other girl, Soni said.
Swati was produced before a local court, which sent her in custody for five days.
Police are looking for other members of the gang.
