Arrests made over New Year's Day DLR attack
Dawn raids by British Transport Police on Thursday saw four arrested in connection with a New Year's Day attack at a DLR station.
It follows an appeal earlier this week for information on suspects to a stabbing attack on a 17-year-old at Tower Gateway.
The victim was set upon by a group of men armed with a bottle and a sharp object after celebrating the New Year.
He needed stitches to his head, cheek and hands.
The BTP raids took place across east London, including an address on the Isle of Dogs.
Chief Superintendent Paul Brogden, from British Transport Police, said: "Fortunately this type of crime is extremely rare on the Dockland Light Railway and the chances of becoming a victim are very slim.
"However, BTP takes incidents like this very seriously and we will do everything in our power to bring the offenders to justice.
"Our investigation remains ongoing but we would still like to hear from anyone with information about the incident.
"I'd like to thank the public for coming forward with information and the media for their assistance with the investigation."
