A window at San Jose City Hall was damaged by gunfire early Wednesday morning, police said.

Officers responded to the building at the corner of Sixth and Santa Clara streets around 6:30 a.m., said Officer Albert Morales, a San Jose police spokesman. When police arrived, they confirmed a bullet hit the window. No injuries were reported.

Morales said the shooting occurred between 1:30 a.m. and 2 a.m. and that no suspects were identified.

“It’s concerning to us. We take it seriously,” said city spokesman David Vossbrink.

The city hall has 24-hour security patrol but no one reported hearing gunshots in the middle of the night, Vossbrink said. Officials recovered security footage that will be used in the investigation.

The shooting came just days days after San Jose Mayor Sam Liccardo and police department officials were criticized by presumptive Republican nominee Donald Trump and his supporters after violence erupted outside Thursday’s Trump rally in San Jose.

Trump went on Twitter and Facebook to accuse Liccardo of doing “a terrible job of ordering the protection of innocent people.”

Vossbrink said there was no credible evidence that the City Hall shooting was related to violence at the Trump rally.

San Jose police released the identities of four teenagers arrested outside the rally on Tuesday. Trump referred to protesters at the event as “thugs” and “illegals.”

Liccardo condemned the violence on Twitter, while noting such behavior was not uncommon at Trump events.

“It is regrettable that this has become a pattern for cities hosting Mr. Trump across the nation,” Liccardo tweeted.
