Ram raiders escaped with cash and cigarettes after targeting a convenience store in Bury St Edmunds early on Wednesday morning.
The burglars smashed their way into the One Stop Shop in Cadogan Road.
Police say they were alerted to the incident just after 1am after an alarm was triggered at the shop.
On Wednesday morning a police cordon was around the damaged front of the shop while officers carried out their investigation.
Staff were also outside waiting for damage assessors to visit and for repairs to be carried out to the front door which had clearly been dented in.
Shoppers looked shocked as they arrived to see the store closed and cordoned off.
A police spokeswomen said: “Police are very keen to speak to anyone who was in the area in the early hours of this morning, who may have witnessed this incident.
“Calls should be made to Bury St Edmunds CID on 101 or Crimestoppers on 0800 555 111.”
Spokeswoman for the One Stop Shop Hannah Carolin, speaking late on Wednesday afternoon said: “The store was closed at the time of this incident, and we’re relieved that none of our colleagues were present.
“The store is now open and serving customers again.
“This is a matter for the police and we’ll of course be helping with their investigation in any way we can.”
None of the staff at the store wanted to comment on the incident.
Neighbours meanwhile told how they had slept through the ram-raid without hearing any noise.
“The shop has been targeted a number of time by burglars although I don’t think it has been ram raided before,” said one neigbour who asked not to be named.
She said she had called police before after seeing burglars smash glass in the shop front and then start passing out bottles of alcohol and other items.
