A 12-year-old boy has been arrested in connection with a sexual assault investigation, Toronto police say.

Three women reported incidents involving a suspect with a similar description in the Sentinel Rd. and Fountainhead Rd. area, just north of Finch Ave. W. near York University, police said.

Police allege a boy sexually assaulted one woman, exposed himself to another and engaged in an indecent act with a third.

The first report came in May 30, and the other two occurred the following week, police said.

A boy was arrested Saturday and is charged with sexual assault, indecent exposure and indecent action.

His identity is being withheld under the Youth Criminal Justice Act.

A court date has not been set.
