Pret a Manger, the coffee chain, is calling on members of the public to help find a missing van that delivers food to homeless shelters.
The company, which has been delivering leftovers to charities for 30 years, said the van is one of six "charity run" vehicles.
Police are, it said, investigating an alleged theft after the van disappeared from northeast London on Tuesday.
“We were devastated to hear that one of the vans went missing on Tuesday, especially since the side of the van so proudly states the important work the vehicle does," Nicki Fisher, head of the Pret Foundation Trust, told BuzzFeed News.
“The police are currently investigating the incident but we think our customers could also help by keeping an eye out for the van on the streets near them."
The company tweeted a picture of the van on Thursday morning.
One of our charity vans has sadly gone missing. Please DM if you've seen it (RX14 ATF), it does a very important job
Fisher added: “For the last 10 years our charity vans have been playing a very important role. Every night the fleet of vans pick up unsold food from our London shops and deliver it to homeless shelters across the capital. Together they deliver over 27,000 food items a week."
