Detectives investigating a series of armed robberies hope people may recognise the suspects from their voices.

Different raids occoured between November 28 and December 16 in Portslade, Hangleton and Shoreham last year.

CCTV footage shows the suspects entering an off licence in Queen’s Parade, Hangleton, around 10pm on December 16. In each of the incidents, up to three suspects entered the locations armed with knives or other weapons, threatened or assaulted staff and demanded cash and cigarettes.

Detective Sergeant Chris Lane said: "Although the video does not clearly show the faces of those who entered the shop in Hangleton, their voices can be heard on the soundtrack. One of them repeatedly refers to the other as 'S' and we would like to hear from anyone who recognises them from their voices.

"Please email 101@sussex.pnn.police.uk or call 101 quoting serial 1613 of 16/12. Alternatively, you can contact the independent charity Crimestoppers anonymously on 0800 555 111."

Two men, both aged 18, from Hove and Portslade have been arrested on suspicion of robbery and have been bailed until March 9.
