At least two people were injured Friday when a powerful explosion rocked a police station in the Colombian capital.

The blast, apparently caused by a bomb, occurred around 4:40 p.m. at the rear of the police post in Lourdes Park, located in Bogota's central Chapinero neighborhood.

Two police officers wounded by shrapnel were taken away in ambulances, witnesses said.

Police cordoned off the scene as fire rescue personnel arrived.

Windows in nearby buildings were shattered by the shockwave from the explosion, which was heard blocks away.

Lourdes Park is in a residential area that is also home to many shops.

While authorities have yet to make an official statement about the blast, Bogota Mayor Gustavo Petro alluded to the incident on Twitter, urging people in the vicinity of the park to be careful. EFE
