An off-duty Houston police officer is the subject of an internal investigation after a family claims he broke into their home while chasing down a teenager. The family says it happened Friday in a neighborhood in Kingwood.According to witnesses, the barefoot off-duty officer was chasing a teenager down the street.The boy’s parents want answers about a broken front door glass and witnesses say you can still see an off-duty officer's trail of blood around their home."He put his face to the window and then he punched a hole in the window so he can see through it and then he just opened the door," said Matthew Pifer.Pifer, 16, says it was last Friday when an off-duty Houston police officer who lives nearby chased him and his friend for allegedly no reason.The teen says that officer was barefoot and only wearing a bathing suit as the man barged through and broke his family's front door. Pifer says the officer assaulted him and threatened his sister until a neighbor stepped in to help.Redmond says he asked the officer what triggered the chase as she bandaged his bleeding hand."He said he smelled cigarette smoke," she explained.Pifer claims neither he nor his friends were smoking, just hanging out near a stop sign between his and the accused officer's home.The officer has not been identified. But a spokesman from the Houston Police Department confirms that the internal affairs division has launched an investigation.Pifer's parents say they not only want their door fixed, they say they want to press charges against the accused officer.
