Police have arrested a man on suspicion of contaminating food after items in three supermarkets in west London were found to have been injected with syringes.
Hammersmith & Fulham Council said officers were called at just before 8pm after a man was reported to be shouting abuse at people in the street.
He is alleged to have visited three supermarkets, including Tesco, Waitrose and Sainsbury’s, in Fulham Palace Road, and injected foodstuffs using a number of needles.
The man has been taken into police custody accused of trying to cause public harm or anxiety.
The supermarkets have been closed and crime scenes are in place.
The affected items are believed to be processed meat and microwaveable products, according to the council.
It is currently unknown how many items have been contaminated, or with what substance.
