An elderly Norbury man was temporarily blinded this week after car thieves sprayed his eyes with an unknown substance when they stole his £25,000 Mercedes.

The 65-year-old victim and his 62-year-old wife were targeted in Dalmeny Road just after 10.15pm on June 11 after they parked the car.

Three black men in a grey Fiat Punto pulled up and one jumped out and tried to grab the Mercedes car keys.

As the pair struggled he sprayed the man in the face with what looked like an air freshener and the trio escaped in the Mercedes.

The suspects are 20yrs, 5ft 7ins, with London accents wearing dark baseball caps and blue jeans. Call PC Paul Shinnick on 020 8768 1212.
