Four men from New Hampshire and Massachusetts were arrested after police say they held a Lyman family at gunpoint and sexually assaulted one of the victims.

22-year-old Xavier Watson, 20-year-old Andre Thomas and 19-year-old Vincent Casazza were arrested in New Hampshire earlier this week.

A fourth suspect, 23-year-old Reynan Mora, was arrested Thursday in Lowell, Massachusetts.

Police say the men will be charged with burglary, robbery and theft of a firearm. Watson is also expected to be charged with aggravated assault and unlawful sexual contact.

Police say the men broke into the family's home and held them at gunpoint on Jan. 15. They're accused of stealing guns, cash, some medical marijuana, four cell phones and two laptop computers.

Extradition proceedings have begun to return them to Maine to face the charges.
