Dortmund (Germany) (AFP)
Three explosions hit German football team Borussia Dortmund's bus
last Tuesday (April 11) ahead of a Champions League home game,
injuring a player and a policeman.
Three separate claims of responsiblity have been made so far but
no new suspect has emerged.
Here is what we know and the latest developments in the
- Three explosions -
At around 7:15 pm (1715 GMT) on Tuesday, three explosions
detonated just minutes after Dortmund's team bus left the squad's
hotel heading for their quarter-final, first-leg match against
Monaco at home.
The blast shattered the bus windows, and Spanish international
Marc Bartra, 26, underwent surgery on a broken wrist after he was
hit by flying glass.
A policeman on a motorcycle escorting the team bus suffered
trauma from the noise of the blasts.
The explosive devices containing metal pieces appear to have been
hidden in a hedge and were set off as the bus passed.
The blast had a radius of more than 100 metres (yards), federal
prosecutors said, adding that it was lucky the toll was not
A piece of metal was found bored into the headrest of a bus seat.
The match was postponed for a day.
- Three claims of responsibility -
The probe has been taken over by federal prosecutors, whose remit
includes terror investigations.
Since the attack, three claims of responsibility have emerged.
The first claim, in three identical letters found at the scene,
suggested an Islamist link.
It referred to the Berlin Christmas market attack in December
claimed by the Islamic State group that killed 12 people, as well
as Germany's deployment of Tornado reconnaissance missions as
part of an international anti-IS coalition.
But security sources have since questioned the authenticity of
the letters and experts have suggested that the claim may have
been made to send investigators on the wrong trail.
A second claim, purporting to be from the "anti-fascist" far
left, was made online, but prosecutors quickly cast doubt on it.
The Tagesspiegel newspaper, meanwhile, said it had received a
third claim by email, this time apparently from far-right
The message rails against multiculturalism, saying it was the
motive behind the blasts and threatening another attack.
Frauke Koehler, federal prosecutor spokeswoman, said that
authorities were examining the email, and that her office was
unable as yet to give an assessment of the note.
- 100 investigators -
Investigators said they were examining all leads, with about 100
officers involved in the probe.
"The investigations are continuing in all directions and are
running at full-speed," a spokeswoman from the federal crime
bureau BKA said.
No suspect has emerged after the sole man in custody -- an Iraqi
-- was cleared of involvement.
Nevertheless there are clues to be looked into.
Experts are examining the traces of the bombs, including their
composition and how they were detonated.
Forensic investigators have also combed the site for evidence,
for instance left behind in the hedges when the bombs were
As the blasts happened close to the hotel where the team was
staying, hotel employees and guests have been questioned.
Residents in the area have also been asked for any possible
sightings of suspicious individuals, who could have detonated the
bombs by remote control.
