MURDER inquiry detectives still do not know what killed Professor Steven Rawlings despite a post mortem examination tonight.

Prof Rawlings' body was found at a bungalow in Southmoor last night and a murder investigation was launched.

A post mortem examination was carried out this evening but it has proved inconclusive, a police spokesman said tonight.

A 49-year-old man arrested in the bungalow on suspicion of murder remains in police custody and is likely to do so tonight.

Police and paramedics were called to the bungalow - which is owned by fellow academic Dr Davinder Sivia, who is understood to be in his 40s - in Southmoor shortly after 11.20pm yesterday.

Efforts were made to revive the 50-year-old, who is married and lived in Letcombe Regis, but were fruitless.

Police will not name the arrested man.
