A t-shirt for a K-pop boy band has emerged as a vital clue in a homicide investigation at Preston.

They’re known as the kings of k-pop, and it’s hoped a t-shirt from Big Bang’s 2015 world tour will help homicide squad detectives identify a man whose body was found in a bin on Saturday morning.

The man’s suspected cause of death has not yet been made public.

Homicide squad detectives also haven’t yet found out where the bin is from.

They say the victim is Caucasian, had dark hair and was possibly aged in his 40s.

The Big Bang tour t-shirt he was wearing is white with a picture of a hot rod and all five band members on it.
