Children were left in tears when they realised their toy shop was closed after burglars raided it at the start of half term.
Lego and Sylvanian Families toys were stolen from independent business Toytown in Seaford this week, forcing the store to close on Monday for scenes of crime officers to investigate.
The popular shop reopened the next day but the crime has left owners and staff shocked.
Darren McGee, who owns the shop with his wife Ginette, said: “We were turning away children on the first day of half term.
“When I realised we had been burgled I wanted to cry and be sick at the same time. I felt physically sick.”
Mr McGee estimated the damage and loss of stock would cost between £7,000 and £8,000.
During the night time raid, Lego and Sylvanian Family toys valued at several thousand pounds were stolen from Toytown in the High Street.
Burglars entered the IT shop Red Rooster IT and then made a hole through an internal wall to gain access to Toytown, in a scene reminiscent of a Hollywood crime film.
Initially a door to flats at the back was forced open and the intruders then entered Red Rooster via a window.
They then made a hole through an internal wall in a communal entrance hall to get into the toyshop.
Once inside they also forced open the till and stole about £900 cash, as well as taking the desirable toys.
Police are appealing for information about the burglaries which took place overnight between Sunday February 16 and Monday February 17.
PC Duncan Ford said; “It is possible that the burglars used a vehicle to remove the stolen toys which are all boxed and brand new.
“If anybody saw any suspicious activity in the vicinity of the properties on Sunday evening or overnight, especially at the rear, we would like to hear from them.
“Did you see a vehicle or anybody carrying boxes of toys?
“If you are offered any new boxed Lego or Sylvanian toys, or know anybody who has suddenly acquired quantities of them please contact is via 101 or email email@example.com quoting serial 239 of 17/2.
“You can also call the independent charity Crimestoppers anonymously via 0800 555 111.”
Sussex Police said the burglaries took place between 4pm on Sunday and 8.50am the following morning.
