Part of Bristol city centre has been sealed off after a "suspicious" car was discovered parked illegally outside a police station.
Several streets surrounding Bridewell police station have been closed as a precaution, with cordons in place.
Avon and Somerset Police said investigations were underway.
"We are currently conducting inquiries to establish the owner of the car," a force spokesman said.
"As a precaution we are also assessing the vehicle."
The roads currently subject to the closure are Bridewell Street, Nelson Street, Silver Street, Union Street, Rupert Street and Haymarket.
However, the spokesman said anyone who was parked in the Rupert Street multi-storey car park would be able to collect it.
