NFL prospect and former Baylor defensive end Shawn Oakman who was arrested on a sexual assault charge has been released from a Texas jail after posting $25,000 bond.

Oakman was freed Thursday from the McLennan County Jail in Waco. He was arrested Wednesday.

According to search warrants, investigators took DNA samples from Oakman's mouth and seized his cellphone, which the 24-year-old athlete twice used to reach out to his accuser after he learned he was under investigation.

Shawn Oakman, 24, a former defensive end for Baylor who graduated in December, was arrested Wednesday and accused of sexual assault

Information on an attorney who can speak on Oakman's behalf wasn't immediately available Thursday.

Oakman is accused of forcing a female student into his bedroom, forcibly removing her clothing, pushing her on to his bed and then sexually assaulting her in the early hours of April 3.

The woman claims she met Oakman, who graduated from Baylor in December, at a bar in Waco before agreeing to go back to his apartment where she says she was attacked.

Oakman, who was arrested and booked into jail on Wednesday, admits to sexual contact with the woman but claims it was consensual.

The woman says she was attacked by the 6ft 9ins, 290lbs footballer between 2am and 3am at his apartment in Waco.

In a statement to detectives the woman said she fled his apartment shortly after the attack but left behind items of clothing and an earring.

Police announced that Oakman was being investigated for sexual assault after executing a search warrant at his address later on the day of the alleged attack.

According to an affidavit, seen by the Waco Tribune, officers were looking for clothing, earrings, semen, blood, skin cells, bodily fluid and DNA evidence while searching the property.

Police seized two comforters, a fitted sheet and a flat sheet from the property which were then tested by a sexual assault nurse examiner.

Oakman's arrest was made subsequent to those tests, but police have not said what, if any, evidence had been found.

On April 3 Oakman, who regularly messages fans with Bible quotations and inspiring statements, sent out a tweet that reads: 'The devil will come and try to strip you of everything you worked for.'

That was followed on April 7 by a series of tweets that read: 'I come to you hungry and tired, you give me food and let me sleep I come to you weak, you give me strength and that's deep.

'Only asking that I keep the focus in between the chapters. You give me the word and only ask that I interpret. And give me the eyes that I may recognize the serpent.'

Oakman, who finished last season as Baylor's all-time sack leader, was considered one of the top prospects of the upcoming draft.

He began his college football career at Penn State University but was dropped after stealing a sandwich and drink from a campus store.

Oakman then moved to Baylor where he issued a statement saying: 'I want to show Penn State and that I messed up, but I’m back now.'

This is not the first time in recent years that Baylor football players have been investigated for sexual assault.

In 2014 Tevin Elliott, a former Baylor defensive end from Mount Pleasant, was jailed for 20 years after being convicted on two counts of sexually assaulting a former Baylor student in 2012.

Two other students testified at his trial that he had also sexually assaulted them, and the court heard evidence of a fourth report of sexual assault.
