CUMBERLAND — A Providence County grand jury indicted Gary P. LaMountain, 37, on four counts of first-degree sexual assault and one count of breaking and entering yesterday, according to the state attorney general’s office.

LaMountain, of 5 Crestwood Court, was arrested on Aug. 12 after he allegedly broke into an apartment on Middle Street and raped a 27-year-old woman four times in the early morning hours.

At the time, LaMountain was serving a 15-year suspended sentence for two counts of first-degree sexual assault, eight counts of forgery and counterfeiting, and one count of felony assault.

LaMountain served three years of a five-year prison sentence imposed in 2004 before being released from the Adult Correctional Institutions in Cranston in April 2007. LaMountain has been in the ACI since his August arrest.

On Sept. 27, LaMountain was sentenced to serve the remainder of his 2004 prison sentence (20 years total) after he admitted that his arrest in August violated the conditions of his probation.

Superior Court Judge Gilbert V. Indeglia ruled that LaMountain immediately begin serving the rest of his suspended sentence, less time served since his arrest.

LaMountain will be arraigned on the new charge in Providence County Superior Court on Jan. 9.
