AYER -- A Level 2 sex offender from Florida is facing rape charges after being accused of sexually assaulting a 16-year-old girl at Westford's town beach earlier this month.

Thomas William Hickey, 25, now of Westford, pleaded innocent in Ayer District Court to two counts of rape in connection with an Aug. 8 incident at Forge Beach.

But at a hearing yesterday, prosecutors withdrew a request for a dangerousness hearing, opting instead that Hickey continue to be held without bail until he can be fitted with an electronic monitoring bracelet next Tuesday.

At the hearing on Tuesday, a judge will decide if Hickey will be confined to 24-hour house arrest or be allowed to leave his house during certain hours of the day.

Prosecutor Elizabeth Dunigan alleges that on Aug. 8, the 16-year-old girl was at the beach with her younger brother, who was fishing. Hickey allegedly approached the brother and sister, who did not know Hickey, and told the brother that the fishing was better further down the beach. When the boy moved away to fish, Hickey allegedly raped the girl.

The victim didn't report the incident until Aug. 15.

According to Florida's sex-offender registry, Hickey has two prior sexual-offender convictions.
