LONDON, Ont. - Police in London, Ont., say a 44-year-old man is facing charges in the alleged abduction of two young girls and a sexual assault on one of them.

Police allege the girls -- aged 9 and 11 -- were abducted by a man in a car while walking on a London street on the night of May 24.

Police say the man took the girls to a park and then to a fast food restaurant before returning to the area where they were abducted and dropping one of them off.

Investigators say the second girl was taken to an unknown location, sexually assaulted and then dropped off in the area where the girls were allegedly enticed into the car.

Dieu V Chau is charged with two counts of abduction of a person under 14, sexual assault, and sexual interference.

Police have not said which girl was allegedly assaulted.
