Met launch probe after officers search bereaved mother’s home

A teenager has been found guilty of the murder of 16-year-old Louis Johnson.

The 17-year-old boy, who can’t be named for legal reasons, stabbed Louis just once with a so-called “zombie knife” leaving him with catastrophic injuries, at a busy commuter station during rush hour in January.

Louis’ mother told us the pain of losing her son was amplified “100 times” when the family woke up weeks later to find police officers running up the stairs seeking to arrest him, and handcuffing his 15-year-old brother because he “looked like him”.

The Metropolitan Police have apologised and launched an investigation into how it happened.
