A person is trapped at New Malden station after 'assaulting a guard' while trying to retrieve their mobile phone from the tracks.

The person is reported to be alive and well after falling between the train and the platform.

The official South West Trains Twitter message said: "It appears that person dropped phone, asked Guard to retrieve but train on move, tried to assault guard through window and slipped."
 

British Transport Police have been called. Several trains have been cancelled and services have severe delays.

Tickets are being accepted on buses.

A Walton woman was killed by a train in front of her boyfriend while trying to retrieve her mobile phone in January of this year.
