One person was killed and three others were injured during a shooting at a bowling alley in Pennsylvania Saturday night, police said.

When the police reached the site around 6:45 p.m., they found four people injured with gunshot and one of them lost their lives at the spot.

Police in East Norriton, Pennsylvania, are still searching for a suspect who committed such a heinous crime and are working with Montgomery County detectives to investigate the shooting.

"There is a possibility that additional victims may have been transported to hospitals in private vehicles," the East Norriton Police Department said in a statement on its Facebook page.

East Norriton Police Chief Brandon Pasquale told CNN affiliate KYW that authorities believe there was one shooter in the incident at the Our Town Alley, based on witness accounts.

"This isn't a common occurrence here, this is a relatively safe neighborhood," Pasquale said.
The police chief said authorities don't yet know what led to the shooting 23 miles northwest of Philadelphia.
