A man in hospital is due to be arrested after he was allegedly seen threatening another man while armed with both a machete and a firearm in Wallington.

He was taken to hospital after he was found in Daimler Way suffering a head injury from a reported assault, a Met Police spokeswoman said.

But police believe he was the suspect initially reported after armed officers were called to Roundshaw Park at around 7.45pm on July 9.

She added: “He [the suspect] was found to be in possession of a machete concealed in his waistband.

"A rucksack was also discovered containing a sawn-off shotgun.

“The male was treated by the London Ambulance Service and taken to a south London hospital. His injuries are not believed to be life-threatening.

“Upon discharge, he will be arrested on suspicion of possession of an offensive weapon and possession of a firearm.”

Meanwhile, eight other men were also arrested in De Vere Close a few streets away on suspicion of possessing a firearm.

The Met Police spokeswoman said they were seen “associating with the suspect and attempting to conceal the rucksack”.

No further details have been released on the men by Scotland Yard, but they have since been taken to various police stations across south London.

Police are currently attempting to find another man said to be involved in the incident while officers are continuing with enquiries.
