An Arbroath town centre car park is in lockdown after an incident involving a man in a flat.
Witnesses suggest police have been involved in a stand-off with the man since early on Friday morning.
A heavy police presence began assembling from 8am at the Marketgate car park in the heart of the Angus town. Part of the area has been cordoned off.
A car is said to have been set on fire at the same address only two weeks previously.
One female neighbour, who did not wish to be named, said: “I have children in the house. It is making me feel nervous and my legs are shaking.”
Another local resident added: “I got such a shock when I saw the riot vans outside the windows. I don’t know what is going on.”
There are reports on social media of some neighbours being unable to leave their properties.
The Scottish Fire and Rescue Service is also in attendance.
A Police Scotland spokesman said: “Officers are currently in attendance at Marketgate in Arbroath dealing with a man at a flat.
“The incident is contained and there no risk to the wider public.
“Residents are thanked for their patience and understanding while the incident is ongoing.”
A large number of police officers could be seen coming and going from the nearby Salvation Army building, where they are believed to have been coordinating the operation.
