Shots were fired outside the Houston office of Rep. Gene Green Tuesday morning, the Texas Democrat’s office said.

At around 11 a.m. Tuesday, several shots were fired outside the building where Green’s Houston North district office is located. The shots hit several windows; some of Green’s staffers were in the office, while the lawmaker himself was at meetings and not at the office at the time. No one was injured, Green’s office said.

The congressman’s office notified the Capitol Police of the incident, and the Harris County Sheriff’s Office and the Houston Police Department said after conducting an investigation that the situation was safe.

Green did not appear to be targeted, as the Lone Star College building next door was also hit and several windows shattered, according to the congressman’s office.

News of the incident was first reported by the Houston Chronicle. A Houston Police Department spokesman told the newspaper that the shots were fired by “a BB gun or a pellet gun most likely.”
