After a two-day manhunt, German police have captured a Syrian man believed to have been planning a jihadist bomb attack.

Jaber Al-Bakr, who arrived in Germany as a refugee, was detained in a flat in the eastern city of Leipzig in the early hours of Monday.

He had sought help from another Syrian, who had alerted police and tied him up, reports say.

The hunt began after police found explosives at Mr al-Bakr's flat.

In the initial raid in the eastern town of Chemnitz early on Saturday, Mr al-Bakr, 22, evaded capture as officers fired a warning shot in a botched attempt to stop him.

Police then found a detonator, explosives and a kilo of chemicals in his Chemnitz flat. Unconfirmed reports suggest the substance was TATP, a homemade explosive used jihadist attacks in Paris and Brussels over the past year.

Security sources referred to Mr al-Bakr's apartment as a "a virtual bomb-making lab", and carried out a controlled explosion. German authorities feared a possible plan to target an airport in Berlin.

As the search for the suspect broadened, a police commando unit arrested another man in Chemnitz, blasting open the door of his home.

However, it was not until late on Sunday night that police were given a tip-off from another Syrian man living in Leipzig who had been contacted by Jaber al-Bakr from the city's main station.

At 00:42 on Monday morning, police burst into the flat in the Paunsdorf area of the city and found the suspect already tied up, Germany's Spiegel website reported.
