A raid in Sheffield in which cooking pots worth £4,000 were stolen was captured on CCTV.
The pots were taken from a van used as a storage unit in a garden on Staniforth Road, Darnall, following the closure of an Indian restaurant.
Kaiser Hussain, aged 26, whose family ran The Spice Lounge in Sheffield, said the cooking pots were rented out to caterers and for large events following the closure of the restaurant.
Three men were captured on camera stealing the pots and loading them into another van on Thursday, March 2.
A £500 reward has been offered for the return of the pots and arrest and conviction of those involved in the raid.
The incident has been reported to South Yorkshire Police.
Mr Hussain said he suspects that the culprits planned the raid.
"We had been storing the cooking pots in a disused van in our back yard since our restaurant closed and we would rent them out to caterers or people having big events if they needed them," he said.
"There were about 25 metal industrial sized catering pots altogether, which we really want back but our fear is that they have been sold on or scrapped because they would have weighed quite a lot.
"It took around 30 minutes for the van to be cleared. It seems to me that they knew exactly what they were coming for and that it was pre-planned.
"I think it must be somebody who knows us, which makes it worse."
A South Yorkshire Police spokesman said: “We are currently investigating the reported burglary and I would urge everyone to be extra vigilant and ensure that all property is kept out of site in a locked secure location.
“South Yorkshire Police are committed to keeping all of our residents safe and anyone with information about the incident is asked to contact police."
Anyone with information should call South Yorkshire Police on 101 or Crimestoppers on 0800 555111.
