AUGUSTA — A China man was indicted Friday by a grand jury in Kennebec County Superior Court on charges relating to a home invasion last summer in which a woman was sexually assaulted.

James A. Bickford, 33, who police said lived in the victim’s apartment before she did, was indicted on charges of robbery, gross sexual assault, burglary and assault in connection with the July 29 attack in China.

According to an affidavit by Kennebec County Sheriff’s Detective David Bucknam, the 21-year-old victim locked her residence on Dirigo Road at approximately 10:20 p.m., after her husband left for work.

Ten minutes later, a man came in the door, his face disguised by a ski mask. He demanded money and threatened to pull out a gun.

He sexually assaulted her, the affidavit said. She was later able to escape to a neighboring house. Bickford was arrested shortly after.

An indictment is not a determination of guilt, but it is an indication that there is sufficient evidence to proceed with formal charges and a trial in superior court.

A number of other people were indicted Friday:

* Frank R. Bowman Jr., 49, of Fairfield, five counts each of burglary, theft by unauthorized taking and criminal mischief, and one count of burglary of a motor vehicle, between Feb. 25 and Aug. 9, all in Waterville.
