WEST HAVEN, Conn. -- A months-long investigation ended in the arrest of man police accused of assaulting an underage girl and possessing a plethora of child pornography.

Kenneth Bothwell, 43, of West Haven, turned himself in to police Thursday on charges of sexual assault, risk of injury to a minor, illegal possession of child pornography and importing child pornography.

West Haven police said their investigation into Bothwell's conduct began in June after receiving a report of sexual assault involving a 12-year-old.

Police issued a warrant and searched Bothwell's Elm Street home on June 21. Investigators said they seized computers and other items from the home.

Police said images from the computers were forwarded to the National Center for Exploited Children -- Child Victim Identification Program. The center confirmed that the subjects of several photos were known victims in the U.S. and U.K.

"We have another, at least one other suspect in mind, and we are recovering several thousand suspected child pornography pictures," said Detective Robert Voets.

Bothwell was released on a $100,000 bond.
