A 16-year-old boy is among three people arrested over the death of a Czech man following a row in a chicken shop.
Two men, aged 19 and 29, and the 16-year-old have been arrested on suspicion of murder and taken to east London police stations for questioning.
Officers believe he was involved in an altercation with a group of men inside Perfect Fried Chicken in East India Dock Road before being followed down the street and attacked.
A Metropolitan Police spokesman said: “Detectives continue to appeal for anyone who was in the area who witnessed the events prior to attack or the incident itself. They retain an open mind as to the motive for the attack.”
A post-mortem examination on Friday revealed he died from head injuries.
His next of kin has been informed.
