Four men have been arrested in connection with a home invasion in Lyman last week.

The intruders held a family of five at gunpoint and sexually assaulted one family member before stealing guns, money, medical marijuana and electronic equipment, according to Maine State Police.

Xavier Watson, 22, of Brentwood, New Hampshire; Andre Thomas, 20, of Lawrence, Massachusetts; and Vincent Casazza, 19, of Newmarket, New Hampshire, were arrested over the past two days.

Reynan Mora, 23, of Lowell, Massachusetts, was arrested in that city Thursday.

Some of the items stolen from the home were found in Mora’s possession.

State police worked with the U.S. Marshal Service’s violent offenders task force and Nashua, N.H., police to locate the men. Massachusetts State Police and Lowell police assisted in Mora’s arrest.

Watson was taken into custody by the federal task force Tuesday in Brentwood and Thomas and Casazza were arrested Wednesday night in Nashua by Nashua police.

The men face charges of burglary, robbery and theft of a firearm when they are returned to Maine. Extradition proceedings have begun.

Watson will also be charged with aggravated assault and unlawful sexual contact.

He is being held at the Rockingham County Jail in New Hampshire.

State Trooper Jonathan Heimbach, who headed the investigation, said four men entered the home in Lyman on Jan. 15 and held the occupants at gunpoint as they ransacked the house.

Two shotguns and a rifle, several hundred dollars in cash, medical marijuana, four cellphones and two laptop computers were taken.
