A wealthy neighbourhood is being targeted by vandals suspected of smashing the windows of more than 60 homes and cars in “drive-by BB gun” attacks.

A £120,000 Audi R8, a £75,000 Porsche 911 and at least three Land Rover Discoveries are among high-end vehicles in Balham which have had their windows damaged.

Properties in the area, where four bedroom homes are worth £1.5 million, have also been hit by ball bearings in the attacks.

It is thought the projectiles are being fired from a vehicle by a gun or catapult.

Police have been passed CCTV showing a car travelling past the Porsche when its window was smashed.

Mother of three Elina Minami, 41, whose friend’s car was targeted, said: “It’s made everyone quite worried. I saw in the morning all these car windows smashed and a window of a house.

"It’s scary really. Why someone is targeting the area I don’t know but it’s made everyone a bit on edge.”

Project manager Victoria Jacobs’s £35,000 Range Rover Vogue was hit outside her home in Calbourne Road where she lives with her husband, a former Navy lieutenant.

She said: “It’s absolutely shocking. My husband saw it and said, ‘It looks like someone has shot the window with an air rifle’.

“I said, ‘Don’t be stupid, this is Balham’. But he was right, I can’t believe it. I’m frightened it will escalate. Will it be animals next?”

Another victim, whose Range Rover was damaged when a ball bearing was fired through the back windscreen outside her £2 million home in Nightingale Square, said: “It’s clear someone was on a joyride randomly shooting.

"They have been firing into domestic windows as well as cars. What if there was a child by the window who was seriously hurt or hit in the eye — they could be blinded?”

Mother-of-three Esther Davies, 42, a trainee teacher, had her Volkswagen people carrier targeted nearby some time on Saturday, February 18, with two windows smashed.

She said: “There were two round circles like bulletholes where the pellets went in. There was glass showered all over the street.”

Another victim, a mother, 35, whose £10,000 Golf R32 had its back windscreen shattered by a pellet on Sunday, February 19, said: “It seems someone is targeting the nicer cars.

“Autoglass said they had fixed seven or eight that day, all nice cars. I think these people chose the area because it’s affluent.”

A neighbour of a City banker whose £120,000 Audi R8 was fired at, leaving it with a broken rear windscreen, said: “It’s outrageous. This area is full of children and if someone is shooting like this, eventually there’s going to be a terrible accident.”

Neighbourhood watch co-ordinator Michael Leech said: “It’s very worrying. The ball bearings are likely being fired from a gun or possibly a catapult, we believe from a vehicle.”

Jonathan Cook, Wandsworth council’s community safety spokesman, said: “We will be checking footage from our very extensive network of CCTV cameras to try to identify the vehicle involved and make sure that those behind these mindless and disgraceful incidents are brought to justice.”
