THREE men arrested on suspicion of a string of sex-related offences after police raided Oxford's Nanford Guest House this morning have been released on bail.

Police investigating alleged child sex exploitation swooped on the Iffley Road bed and breakfast at 7.50am today.

Three men, aged 81, 49 and 48, were arrested on suspicion of three offences each - being a landlord letting a premise for use as a brothel, causing or inciting child prostitution for gain and encouraging / assisting in an offence believing it will be committed, namely rape and arranging child prostiution for gain.

The 48-year-old and 49-year-old have tonight been released on bail until September 4.

The 81-year-old has been bailed until tomorrow morning.

Police also raided a property in Sunningwell Road, Sunningwell, at the same time.

Sixty officers were involved in total, include some from Thames Valley Police's Operation Bullfinch team, which is targeting alleged child sex exploitation.

Firefighters and environmental health officers were also at the scene of the raid.

It comes after seven men were convicted of child sex offences in Oxford including trafficking and facilitating prostitution at the Old Bailey last month.

The warrant was issued under section 8 of the Police and Criminal Evidence Act. Police said it was in relation to information that came to light during the recent Old Bailey trial where evidence was heard that the guesthouse had been used to facilitate child sexual exploitation.
