A Dubai court has sentenced three British tourists to four years in prison on drug charges in a case that drew international scrutiny over claims of abuses in custody.

The allegations of torture brought a statement of concern from British Prime Minister David Cameron, but Dubai authorities have denied any wrongdoing.

The trio, identified as Suneet Jeerh, Grant Cameron and Karl Williams, were arrested last July with what police said was the synthetic drug known as Spice. The men deny the charges. They claimed they faced abuse by police, including electric shocks and beatings.

Monday's conviction and sentence can be appealed within 15 days. The court also ordered the men deported after they complete their sentences.
