A man has been caught carrying drugs and a blade more than half a foot long in Norwich.

Police seized the drugs and knife near Lawson Road on Monday evening.

A man was arrested at around 6.50pm and taken into police custody for being concerned in the supply of drugs and for possessing an offensive weapon.

A police spokesman said the drugs are yet to be tested.

Norwich police tweeted a photo of the knife which covers the length of a 30cm ruler, with the blade going just over seven inches.
