TEWKSBURY -- An undercover prostitution operation conducted Monday resulted in the arrests of three out-of-state women at two town hotels, according to police.

Megan Sullivan-Albee of Bangor, Maine and Megan Horsfield of Manchester, NH, both 24, were arrested at the Hoilday Inn on Highwood Drive and charged with sexual conduct for a fee.

Horsfield, who police said had two outstanding warrants, was also charged with possession of heroin and possession of crack cocaine.

Twenty-year-old Violet Harris of Hartford, Conn. was arrested at the Fairfield Inn on Andover Street for sexual conduct for a fee.

Tewksbury police occasionally conduct prostitution stings at some of the town's hotels, in response to solicitation on websites like Craigslist.

An operation in September resulted in five arrests, including three at the Motel 6 on Main Street, one at the Holiday Inn and one at the Residence Inn on Andover St.

Including those five, Tewksbury Police arrested nine people for prostitution in 2013. Eight of the arrests were at hotels.

Sullivan-Albee, Horsfield and Harris were scheduled to be arraigned Tuesday in Lowell District Court.
