After a food truck exploded at a charity event in England, five people were hospitalized, including four people working at the event.

The incident happened at The Lambing Shed Farm Shop and Kitchen in Knutsford on Saturday, Feb. 21, around 1 p.m. local time, a Cheshire Police spokesperson told BBC, which reported that a gas canister exploded at the event in support of the North West Air Ambulance Charity.

The five people were treated by paramedics on the scene. They were then transported to the hospital with non life-threatening injuries, per the police.

The incident is not being treated as suspicious.

PEOPLE reached out to Cheshire Police and the Cheshire Police and Crime Commissioner for more information, but did not receive immediate replies.

The Lambing Shed Farm Shop and Kitchen, also known as the Moseley Hall Farm, is about 20 miles south of Manchester.

The venue addressed the incident on Facebook, stating that it involved “our food truck” and that four members of their team were injured.

“They are currently receiving medical care and are being supported by their families,” the farm wrote of their injured employees.

“We are extremely grateful to the emergency responders for their swift and professional assistance,” the statement continued.

The farm promptly canceled the second day of the event and closed its other amenities to prioritize the health of their team.

“Our thoughts are with our injured colleagues and everyone affected. We are cooperating fully with the relevant authorities as they look into what happened and will share further updates when appropriate,” the statement concluded.

Attendee Daniella Grainger-Leigh commented on the Facebook post and stated that she was at the event with her two young children during the incident.

“[It] was pretty scary and [I] think [a] fair few people shook up. My boys were, my older one still not himself,” she wrote. “Heart goes out to the people injured [and] I wish them a speedy recovery.”

The farm is a family business run by owners Michael and Sue, and their daughter, director Kathryn, according to their website.

Both days of the event, Big Machine Weekend, were sold out, per the website.

The ticketed event advertised large tractors and big machinery, a bouncy castle and a selection of food and drinks.
