Armed police descended on Mitcham this morning after a man was reportedly threatened with a firearm.

Police were called to Shelley Way in Colliers Wood at 8.20am where a man said he was confronted by someone who claimed to have a firearm, although no weapon was seen.

About 10 officers later closed in on Miles Road in Mitcham as they searched for a suspect, while a police helicopter circled overhead.

Carol Manger, who lives in Miles Road, said: "I saw them going from place to place and at one time they were surrounding a block of flats down the road.

"They were also in Venus Mews for quite some time. "

Police cordoned off Church Road and Miles Road at about 9.30am and remained in the area for about an hour.

No arrests have been made.

Merton Police are investigating.
