Windows in a seafront shelter on The Esplanade in Seaford were damaged on Sunday December 28. Sussex Police were alerted about the damage at about 9.30pm the same day.
A group of two or three boys was seen in the area at the time and enquiries are continuing. No arrests have been made. The refurbished beach shelter was one of a number of measures taken to improve the seafront by Seaford Town Council last summer.
It had been vandalised in February last year when the majority of the glass panels were smashed. Anyone with information on the latest incident is asked to email firstname.lastname@example.org or call 101 quoting serial 1217 of 28/12.
