Los Angeles police have released a sketch of a man they say tied up and raped two women from Skid Row in the past two weeks.

A police statement says a middle-aged, balding man in a brown van gave a 37-year-old homeless woman a ride on Aug. 1, bound her with duct tape and then raped her repeatedly over the next three days before dropping her off in Koreatown.

Police say a man matching the same description picked up a 29-year-old woman on Monday night and offered her a ride to get food. The van drove to a McDonald’s but when the woman refused to perform a sex act, police say the man pulled a knife, bound her with duct tape and drove to Alhambra, where he raped her.

Police say he threw her in a trash bin before fleeing.
