More than 1,500 people were caught for traffic offences during a week-long crackdown on dangerous driving.

Metropolitan Police and Transport for London targeted dangerous drivers in a week of action, which results in more than 1,500 people being caught and 25 arrests.

The arrests included five drink or drug driving offences, disqualified driving, assault, drugs and immigration offences.

There were also 636 drivers caught using mobile phones, which can be subject to a £200 fine and six points added to the driving licence.

Research has found people using a mobile phone while driving are four times more likely to be involved in a crash, and that drivers texting at the wheel are 23 times more likely to be involved in a crash compared to a driver paying full attention.

Siwan Hayward, head of transport policing at TfL, said: "We want to send out the clear message that if you drive in London and flout the rules, you will be caught.

"We want London's streets to feel safe for everyone and will continue to crack down on dangerous drivers.

"The Mayor has set out a clear ambition in adopting Vison Zero that TfL, the police, boroughs and the community must work together to create a road network which is free from death or seriously injury.

"This week of action shows what we can do together and is the start of a major shift."

Officers were patrolling in an unmarked HGV cab, giving them an elevated position to spot motorists driving with a phone.

Commander Neil Jerome, of the Territorial Policing Command, said: "This operation was about reminding all road users of the importance of keeping themselves safe while driving.

"I hope our policing activity achieved just that and motorists can certainly expect to see us carrying out similar operations throughout the year to ensure they are concentrating on safe driving."
