Life-saving equipment, including a specially designed knife, has been stolen from a coastguard boat in Newhaven.
It happened after a training exercise carried out at the UTC college in the town's harbour on July 15.
A seatbelt cutter and a windscreen hammer also went missing.
A member of the public handed in an empty medical case found in Lawes Avenue in the early hours of July 21st.
Police are asking residents to hand the equipment in if found - they're concerned the knife could be dangerous in the wrong hands.
PC Anna Batchelor is appealing for information to find the knife, which has distinctive SPYDERCO writing on the side and a small image of a spider crab. It is made of special steel designed not to rust in water.
The officer said:
“We are concerned that this is an expensive piece of equipment which may be dangerous if it is in the wrong hands.
“Officers want residents in Newhaven, especially parents of teenagers, to inform us if the knife is found.
“If anyone has any information please report it to us online or call 101 and quote reference 47210122539 of 21/07.”
