The suspected theft happened on Tuesday (28 February) around 18:50.
“A passenger travelling to Jersey from London on Easyjet flight EZY897 had placed their black Mulberry carry-on suitcase in the overhead lockers above rows 4 -6 on the plane, a few rows in front of where they were actually seated,” officers explained in an appeal for more information.
“On leaving the plane, they discovered that their bag was no longer where they had placed it and had been taken as the passengers disembarked the plane on arrival in Jersey.”
They described the bag as being made from black fabric and carrying a Mulberry motif, with two small wheels and a pull-up handle.
“There is a black leather tag on the case with the owners UK details and it had a worn Flybe sticker on the handle,” Police added.
