A 15-year-old boy has been arrested after a teenager was stabbed to death in a skate park in Slough.
The victim, also 15, was attacked in Salt Hill Park at about 6.30pm on Saturday.
The teenager's death followed a row involving a group of men.
Officers believe all of those involved in the incident were known to each other and that it was not a random attack.
The boy was pronounced dead at the scene but has not been formally identified.
His family have been informed.
Detective Chief Inspector Andy Shearwood, of the Thames Valley Police Major Crime Unit, said: "This is a fast-moving investigation and we have made an early arrest as we continue to carry out our enquiries.
