A shop worker has said he was “glad there were no customers” in his family’s store when arsonists set it alight, getting scorched in the process.

Dramatic footage shows the hooded trio, with their faces covered, walking into Zafs Go Local in Butler Street, Manchester, at about 17:40 BST on Sunday.

One man pours petrol on the floor and another man lights the fire, while a third man appears to be filming it on his phone.

Two men end up setting themselves on fire as flames quickly erupt and they run out of the shop.

The staff member, who does not want to be named, told the BBC he had “no idea” why the shop was targeted.

He said the store had never faced any major incident in Ancoats, where it had operated for about 10 years.

Sunday was usually a “quiet day”, he added, with the arsonists turning up “out of the blue”.

“I was behind the counter and they poured petrol on the floor and lit it up,” he said.

“Rather than staying put, being scared and freezing, we just moved and did something by putting the flames out with a fire extinguisher.

“I’m just glad there were no customers in the shop as they could have got scared.”

Emergency services attended and said no-one was injured and no arrests had yet been made.

Greater Manchester Police said an investigation was under way and appealed for information, adding that “enquiries are ongoing into locating the three men”.

The shopkeeper said the incident was over in “about 10 seconds”, but parts of the ceiling, counter and floor were damaged.

He said the shop reopened shortly after,”to show we’re not scared, not intimidated”.
