A young, tall man is being sought by police after a suspicious death in Perth's south more than two weeks ago.

Paramedics found a 70-year-old man's body at a home in Warnbro on June 1, a Western Australian police spokeswoman said on Monday.

His death was referred to the Major Crime Division detectives after a post-mortem examination found injuries indicating suspicious circumstances.

Police are appealing for information from anyone who spotted a tall male aged in his early 20s wearing dark clothing near Okehampton Road and Parkland Drive in Warnbro.
