A Canadian man who was held captive by a faction of the Afghan Taliban for five years has been arrested on 15 charges, including sexual assault, illegal confinement and issuing death threats, according to reports on Tuesday.

Joshua Boyle was freed last October along with his American wife Caitlan Coleman and their three children born in captivity.

The identity of the alleged victim was being withheld by a court, according to Boyle’s lawyer Eric Granger.

Granger added his client was “presumed innocent” and had never been in any form of legal trouble before.

“We look forward to receiving the evidence and defending him against these charges,” he said, adding Boyle would appear before a court in Ottawa on Wednesday.

According to news channel CTV, Boyle is facing eight counts of assault, two counts of sexual assault and two counts of unlawful confinement, as well as one each of misleading police to “divert suspicion from himself”, uttering a death threat, and administering a noxious substance, Trazodone.

In a statement to The Toronto Star and published on the newspaper´s website, Boyle’s wife would not comment on the specific charges “but I can say that ultimately it is the strain and trauma he was forced to endure for so many years and the effects that that had on his mental state that is most culpable for this”.

She said, “with compassion and forgiveness that I… hope help and healing can be found for him”.

Coleman added that she and the children were healthy.

Boyle and Coleman, who have been married since 2011, were kidnapped by the Taliban during what they described as a backpacking trip through war-torn Afghanistan in 2012, and were later transferred to the custody of the Haqqani faction.

They were freed on October 12 by the Pakistan Army, but refused to board a US military plane. Boyle, a Muslim convert and long-time advocate of freed Guantanamo inmate Omar Khadr, cited fears over his background.

Upon his arrival in Toronto two days later Boyle accused his captors of raping his wife and killing his baby daughter, a fourth child — allegations swiftly refuted by the Taliban.

A Taliban spokesman admitted a baby had died but said it was a result of a natural miscarriage.

A month later Coleman also spoke of a sexual “assault” by two of her captors in an interview with ABC news.

Boyle has been an outspoken advocate for Omar Khadr, a Canadian captured at the age of 15 in 2002 in Afghanistan and held at Guantanamo Bay before being transferred to Canada and later released.

He married Khadr’s sister in 2009.
