A man identified by police as a convicted sex criminal was arrested late Tuesday after a gunshot was fired at a suspected Lockport drug house.

Kenneth W. Houghton Jr., 31, of Walnut Street, was arrested on numerous charges after officers responded to a call of shots fired at a building at 107 Genesee St., Lockport police reported.

At about 10 p.m., a large-caliber bullet penetrated an outside wall and a door at a house at 119 Genesee before lodging in another wall in the house, Detective Lt. Scott D. Seekins said. No one was hit by the gunshot.

An unattended 12-gauge shotgun was found on a rear porch a few doors away at 119 Genesee, police said.

“Investigators determined that [Houghton] was believed to be the shooter, and we believe the incident was connected to drug activity,” Seekins said.

According to police, Houghton has been arrested five times this year, and has a past record of 11 misdemeanor convictions and one felony conviction. Police said Houghton was convicted of misdemeanor sexual misconduct in connection with a 2005 incident, and because of that conviction is on probation until January 2014.

Police charged Houghton late Tuesday with felonies of criminal mischief, reckless endangerment, assault, conspiracy, and criminal possession of a firearm. He was also charged with a misdemeanor count of menacing.

The block of Genesee Street where the incident took place is known to police for illegal drug activity, Seekins said.

Detective Kenneth Schrader suffered a broken thumb when Houghton allegedly struggled with him after being advised of the charges against him, police said.
