Police are appealing for witnesses after a gang of masked men raided two south London bookmakers on Halloween.
Three suspects wearing Halloween masks entered a branch of Ladbrokes in Tooting at around 11pm on Halloween night.
One suspect threatened staff with two bricks, demanding cash.
After forcing staff to empty tills and fruit machines, the men took off from the bookies on Franciscan Road on foot towards Tooting Bec.
Around 40 minutes later the gang, still wearing masks, entered another Ladbrokes in Croydon Road.
After threatening the staff the men smashed a glass screen with a hammer before making off with a quantity of cash and a watch.
No members of staff were injured during either incident and no arrests have been made.
Detective Sergeant Guy Carmichael from the Flying Squad at Barnes said: "I am appealing for anyone who was in the vicinity of either incident on Halloween evening and who saw the three suspects to contact me.
"Given the time of year there would have been numerous people dressed up but I am releasing images of those involved in the hope that someone will have seen them and can provide us with more details about their movements and identities."
Anyone with information is asked to contact the Flying Squad at Barnes on 0208 247 4804 or call Crimestoppers anonymously on 0800 555 111.
