Police got more than they bargained for when they stumbled on a massive haul of rifles and handguns.

Officers went to a house in Larkfield Way, Brighton, on what they believed a routine operation to secure firearms earlier today.

They discovered a haul of 30 rifles, 40 handguns and a grenade.

The rifles had been decommissioned but many of the handguns were live and loaded. A World War Two hand grenade was also found in the house and the bomb disposal unit were called to make it safe.

Sergeant Chris Lane said: "Let's say it wasn't our usual day at the office.

"We were told we might found two or three firearms at the house but were amazed to find 70.

"The late owner of them who lived at the house was obviously an avid gun collector."

The firearms have been removed by officers and secured and enquiries will be made into their origins.
