Scotland's charity regulator has dealt with 15 separate allegations of sexual misconduct in the last two years, it has emerged.

Two of the cases involve the Scottish Catholic International Aid Fund, which confirmed this week that allegations had been made about two incidents.

The Office of the Scottish Charity Regulator (Oscr) said the rest of the cases involved incidents in the UK linked to Scottish charities.

Six cases involve charities which are part of the Scottish Child Abuse Inquiry, it said, and they will be dealt with by that investigation.

Sciaf said one incident in Burundi involved the alleged rape of a 15-year-old girl in 2012, by a 45-year-old Burundian man who volunteered for a local partner organisation.

Another incident in Ethiopia involved a man who was accused of sexual misconduct with a young boy while working in the shared offices of Sciaf other UK aid charities.

Neither of the alleged victims were assisted by Sciaf and the incidents did not take place during any of the charity's projects.

Director Alistair Dutton said they were dealt with "decisively" and insisted the charity has stringent safeguarding procedures.

"Clearly, there have been reports of troubling incidents within certain organisations," he said.

"Allegations of sexual misconduct are very serious and we do not take them lightly.

"In these instances, we will always take the necessary regulatory action and work with every appropriate body to protect beneficiaries, volunteers and staff.

"There is nothing, however, to suggest that these instances are more common in charities than in other organisations."

Sciaf spoke out about the cases amid increasing scrutiny of the UK aid sector following the Oxfam sexual misconduct scandal.

Oxfam has been accused of concealing the findings of an inquiry into claims staff used prostitutes while delivering aid in Haiti in 2011.
