Furious cyclist smashes driver's windscreen with his own bike

This is the moment a cyclist smashes a driver's windscreen with his own bike after a furious row.
Tracey Leng, 50, was driving to see her mother who is seriously ill at Manchester Royal Infirmary hospital on Mother's Day when she became embroiled in an argument with the unknown cyclist.
Footage from the Levenshulme mother's dashcam shows a cyclist wearing black overtake her at red traffic lights on Hathersage Road in Chorlton-upon-Medlock.
He then tails back to begin an argument with Mrs Leng.
On two occasions he appears as if he is about to ride off before walking back to continue the row. The footage then shows him picking up his bike and throwing it at the dark blue Skoda Octavia, cracking the windscreen.
Mrs Leng says the man had turned around to berate her for veering into a cycle lane - which she insists that she did not do.
He does then get back on the bike and rides off and despite efforts by Tracy and her husband Peter, 44, to follow him he managed to get away cycling through the Manchester Royal Infirmary site.
Police were called and officers, including forensics, attended and took a swab of his saliva he left after spitting on the vehicle.
The mother from Levenshulme, who works as an estimations clerk in the oil and gas industry, claims the man shouted abuse at her during the incident and said she was deeply shocked.
Mrs Leng has passed on footage to GMP and officers are now investigating the shocking incident, which happened at the junction with Upper Brook Street.
A GMP spokesman confirmed the incident had been reported to them and they were investigating.
He said officers are set to examine the footage and both themselves and Mrs Leng are appealing for any witnesses, or anyone who can help with their enquiries, to come forward.
Mrs Leng said: 'We're still a state of shock about it.
'We don't know why he was so angry. There was no clear cycle lane and even if there was I definitely wasn't in it.
'He started shouting and swearing but as soon as we told him it was all being caught on the dashcam he totally flipped.
'We were totally numb after he threw the bike.
'There was a big loud crack, we didn't know if the whole window was going to shatter. It was really frightening, we didn't know what he might do next.'
Mrs Leng's 69 year-old mother is undergoing life-saving surgery in the next few days and she says the attack has inconvenienced them at the worst possible time.
She added: 'Things are bad enough at the moment.
'It completely ruined Mother's Day as we had to cancel a meal and cut short visiting my mum to deal with the police.
'But more importantly my car is off the road now at a time when we really need it to get to the hospital.
'I was just so un-called for, I cannot understand why anyone would do something like that.'
