Six people have been charged after a break-in at the Co-operative Food in the Burghley Centre, Bourne, on Monday night.
Thieves got into the store via the roof and targeted the tobacco kiosk.
It was discovered when staff arrived at work on Tuesday morning and the shop was closed for a short time that morning, while police enquiries were carried out.
Staff from the Co-operative said a “substantial amount of cigarette stock” was stolen.

“The store is trading as normal and we thank customers and colleagues for their support and patience during this time.”
