A 28-year-old shot in the head in Haringey on Saturday (October 14) is fighting for his life in hospital.
Police are appealing for information about the attack in West Green Road at around 12.20am.
Emergency services attended the scene and found the victim, a father to a newborn baby, with a gunshot wound to the head.
He was taken by London Ambulance Service to an east London hospital where he remains in a critical condition.
His family has been notified.
Officers from Trident and Area Command are investigating the incident and enquiries are ongoing.
There have been no arrests and officers retain an open mind as to motive.
DI Jane Topping, of Trident, said: "A young man, who has just become a father for the first time, is now critically injured in hospital. Our enquiries suggest this was a determined attack and the victim had been repeatedly shot at before he was critically injured.
"His family is distraught and we clearly want to identify and locate the suspects for this crime at the earliest opportunity so they can be brought to justice.
"I would ask anyone who knows anything about this terrible crime to think about the devastating effect this has had on this young man and his family. Anyone with information can call police or Crimestoppers - any information will be kept in the strictest confidence."
Any witnesses or anyone with information should contact detectives at Operation Trident on 101 or contact police via Twitter @MetCC.
