A University of Oxford employee and a US microbiology professor suspected of murdering a man in Chicago have handed themselves in after more than a week on the run.

Andrew Warren, 56, a senior treasury assistant at Somerville College - whose famous alumni include former chemistry student Margaret Thatcher - was taken into custody in California, as was Professor Wyndham Lathem, 42.

The two men triggered a nationwide manhunt after allegedly stabbing Trenton Cornell-Duranleau, 26, multiple times in Lathem's apartment on 27 July.

Warren handed himself into a police station in San Francisco, more than 2,000 miles from the alleged crime scene, on Friday evening, while Lathem gave himself up at 7.30pm in Oakland.

Supervisory Deputy US Marshal Frank Conroy said he was unable to give details of Warren's state, but added: "Wyndham surrendered peacefully and seemed to be in good condition.

"They refused to speak to anybody on the advice of counsel."

Mr Conroy said the the men will appear in separate courts in the coming days to face extradition hearings in Chicago where they will face detectives.

Chicago Police spokesman Anthony Guglielmi said: "Both individuals will be held accountable for their actions and we hope today's arrest brings some comfort for the victim's family. We are also thankful that this did not end in further tragedy."

Oxford University had urged Warren to hand himself in and a spokesman said his colleagues were "shocked" to hear of the case.

Warren, who says on Facebook he lives in Swindon, and Lathem, a microbiology professor at Northwestern University, are accused of repeatedly stabbing the victim in the 10th-floor apartment before fleeing.

Mr Cornell-Duranleau was a hairstylist originally from Corunna, Michigan, but was living in Chicago at the time of his death.
