Police are searching for a man they say may know what happened to a sketch artist who was found bloodied, bruised and with parts of her clothes removed at a Brisbane park.

Ioli Hadjilyra, 26, who lived in Spring Hill, was discovered under a railway bridge near a couple of her sketches by a council worker at Clayfield's Kalinga Park on Wednesday.

Police are searching for Bradley Edwards, 34, who they say may have information into the death of Ioli Hadjilyra.

Police deemed her death suspicious after attempts were made to conceal Ms Hadjilyra's body in a garden bed. Detectives could not rule out the possibility that she had been sexually assaulted.

After an appeal for information this week, Detective Senior Sergeant Chris Toohey fronted media on Sunday in the hope of finding Bradley Edwards, 34.
