Statement from BTP:
Following the death of a man at Strawberry Hill railway station yesterday, we are increasing our high visibility patrols in the area this afternoon into the evening and working with our colleagues at Metropolitan Police to provide a visible reassurance to the community.
A murder investigation was launched after a 21-year-old man from the Twickenham area sadly died after he was fatally stabbed at the station.
His family have been informed and are being supported by specialist officers.
Our thoughts remain with them at this tragic time.
This incident is believed to be linked to another incident in Alexandra Close in Twickenham at around 11.57pm.
A 16-year-old received a non-life threatening laceration to his leg.
He is among one of those arrested in connection with the incident at the station.
Four remain in custody, a 19-year-old man, 20-year-old man, a 16-year-old boy and a 15-year-old boy.
Anyone with information that may help us piece together the moments leading up to this to contact BTP or you can call Crimestoppers anonymously on 0800 555 111.
