Police are investigating a series of knife point robberies in Hastings and St Leonards involving a man using a large knife or machete to threaten victims.
Officers said in each case, a man in dark clothing was using the weapon to force victims to hand over mobile phones, bags, jewellery and other personal possessions.
They include two incidents on Wednesday (April, 11), the first of which involved a 17-year-old local boy and his 20-year-old cousin being robbed in Battle Road around 9.30pm.
Around 20 minutes later, a pedestrian was accosted in Stonefield Road, and forced to hand over valuables.
Police said in the first incident, the man was riding a pedal bike, and then a motorcycle in the second.
DC Damon Deans-Cane said:
“We believe there may have been at least three more robberies linked to these incidents and we would like to hear from other victims, witnesses or anyone with information as soon as possible.”
The suspect has been described as a man, possibly black or mixed race, 6′ tall, and in his 20s.
He was wearing a black hat, a black scarf over his face, a dark or dark green coat, black jogging bottoms, and black Nike trainers.
The motorcycle was a red or orange Lexmoto Hunter Moped which looked similar to a Kawasaki or Suzuki.
Police said it had been reported as stolen earlier that evening.
A 26-year-old man has been arrested on suspicion of robbery while enquiries continue.
