A former Special Branch anti-terror detective has reacted to Monday evening's terror axe attack on a German train by saying: "It's fortunate the casualities have been so minimal".
The attack saw a teenager confront around 20 passengers with an axe and a knife shortly after the train left the town of Wurzburg in Bavaria, southern Germany.
Three people were seriously hurt and one sustained light injuries before the attacker was shot dead after fleeing the train.
According to Bavaria's interior minister, Joachim Herrmann, the attacker was a 17-year-old Afghan asylum seeker.
A hand-drawn Islamic State flag was later reported to have been found at the teenager's home, and the self-styled Islamic State terrorist group have claimed responsibility for the attack.
Former detective Dr. David Lowe, now a lecturer on global crime and security at Liverpool John Moores University, told Julia Hartley-Brewer that the attack had "the hallmarks" of being linked to terrorism.
"Perhaps [the attacker] had been inspired by what he'd read, seen, listened to...it has the hallmarks of it," he said.
"It's about determining whether it's organised and part of a [terror] cell, or whether someone has gone out on their own, on their own volition, to do these attacks.
"It's fortunate the casualities have been so minimal."
