Three British teenagers who were arrested in Turkey and barred from travelling any further to Syria have now been released on bail according to a Scotland Yard statement.

Two 17-year-old boys from the Pakistani community in north-west London as well as a 19-year-old man were brought back to the United Kingdom after they were apprehended on Saturday, the met said.

According a report by The Times, UK police had alerted Turkish officials after their parents informed the police about their whereabouts. The counter-terrorism officers were initially told that two 17-year-old boys had gone missing and had possibly boarded a Turkey-bound flight on Friday. When the boys never returned home after their Friday prayers, the parents informed the police, the Times added.

It was only after further investigation that the met discovered that the duo had been travelling with the third slightly older teenager; the UK police have been cited as saying by British media.

"Officers alerted the Turkish authorities who were able to intercept all three males, preventing travel to Syria," a police spokesman said, according to the BBC.

The two boys were stopped by Turkish officials at Istanbul's Sabiha Gokcen airport, who were apparently responding to the inputs from the British intel, reports further say.

"This is a good and a clear example of how the security cooperation between Western intelligence agencies and Turkey should work," the official said.

This comes almost a month after British police announced the departure of three schoolgirls to Syria to join Isis raising worldwide concerns about the growing number of teens been lured into joining the terrorist group.
