Multiple people killed in church shooting in Hamburg, Germany, police say

When police arrived at a Jehovah's Witness church in Hamburg, Germany, in response to a shooting Thursday, they heard a gunshot on the top floor of the building, a police spokesperson said. The building is three stories high, he said.

Hamburg police spokesperson Holger Vehren told CNN affiliate NTV reporter Bastian Vollmer that officers arrived at the church around 9:15 p.m. local time. Police previously said the shooting happened at around 9 p.m. local time.

When law enforcement entered the building, they found several dead and injured people on the bottom floor, the spokesperson said. They found another person dead on the top floor after hearing the gunshot, he said.

Police believe the person on the top floor may have been a gunman but said no further information could be given at this point, according to Vehren. There are currently no indications that a suspect is on the run, the police spokesperson said.

Hamburg Police said in a translated tweet that officers are "working at full speed." They urged people to refrain from talking about any potential gunman or the shooting itself.

"You would make it much easier for us to communicate about the ongoing operation" in the GroßBorstel district, another translated tweet read.
