Police probing an early morning brawl at McDonald's have made a third arrest.

Violence erupted at the restaurant in Commercial Road, Strood, at 3.20am on Saturday, April 20.

An onlooker filmed the fracas and later posted the video on Facebook.

It appears to show three young men attacking a security guard who falls to the floor.

At one point one of the men appears to throw a wet floor sign at the stricken man.

Officers made two arrests last month and have now revealed a third suspect has also been tracked down.

The 19-year-old from Strood was arrested on suspicion of affray at 10am on May 1.

A 24-year-old and a 23-year-old man, both from Rochester, were arrested on suspicion of the same offence on April 25.

Spokesman James Walker said: "At present, there have been no charges relating to the altercation that took place at the Strood McDonald’s. Inquiries remain ongoing."

All three have been released pending further enquiries.

After the incident a McDonald’s spokesman said: “The safety and security of our people and customers is our absolute priority, and it is extremely disappointing to see this sort of behaviour in the restaurant.

"We do not tolerate any form of violence or abuse and will be cooperating fully with the police investigation.”
