A murder inquiry has been launched after the battered body of a teenager was found in a park in West Yorkshire.
Detectives said the youth, aged 17 or 18, was found in Crow Nest Park in Dewsbury at 1930 BST on Sunday.
The teenager, who was Asian, was found in a walled garden by two members of the public who rang for an ambulance.
Det Supt Chris Thompson, of West Yorkshire Police, said: "This young man was subjected to a sustained and brutal attack."
Mr Thompson, who is leading the investigation, said a post-mortem examination was expected later. He refused to say whether a murder weapon had been used.
"As it was a sunny day it was very busy and there was a large number of young people in the park," he said.
"I'm anxious to trace these people in order that we can paint a picture of events leading up to this incident. At this moment, the motive is unclear."
The youth was dressed in white tracksuit bottoms and a white Bench top.
The area where his body was found had recently been transformed into a wildlife garden. Police have closed the whole of Crow Nest Park to the public while investigations continue.
The park, which opened to the public in 1893, contains an ornamental lake, museum, terraced walks, a woodland garden, and promenades.
