Two teenagers were robbed by a gang of youths on Monday evening while walking through Bexhill town centre
The boy and girl were walking in Endwell Road at about 8.25pm on February 24 when they were threatened by the gang.
Items including a Canada Goose coat and a Nike rucksack were taken.
The victims had walked across the railway bridge and later went towards a nearby shop where police were called.
They were left shaken by the incident but have received support from officers.
Officers attended the area and a 21-year-old man was arrested on suspicion of robbery. He has been bailed with strict conditions.
It is believed others from the group had approached the victims from the Devonshire Square area.
Patrols have been stepped up in the area to provide an extra level of visible reassurance.
Witnesses or anyone with relevant information such as mobile phone, CCTV, dashcam or doorbell footage in the area at the time is asked to come forward.
In particular, if anyone saw a group of young people acting suspiciously in the area at the time, they are asked to come forward.
Information can be reported to Sussex Police online or on 101, quoting serial 1242 of 24/02.
