A burglar stole a red mobility scooter and £20 worth of frozen meals from a garage in Peacehaven.
The building in Friars Avenue was broken into overnight between 9.30pm on Saturday August 31 and Sunday September 1.
PC Anna Batchelor said: “The elderly occupant had only bought the scooter in the last month to help him stay independent.
“He has been left particularly upset by this incident and I am appealing for any information which will lead to the recovery of his scooter.”
Anyone with information should call Sussex Police on the non emergency number 101 quoting serial 506 of 1 September or the independent charity Crimestoppers anonymously on 0800 555111.
