BERLIN, Feb. 18 (Xinhua) -- A teacher was killed by an attacker in a vocational school in the western German city of Ludwigshafen Thursday morning, local media quoted police as saying.
A 23-year-old was arrested as the suspected perpetrator, local police said.
Local media reported that several teachers were attacked. The weapon used by the attacker is said to be a knife.
The school was sealed off and evacuated immediately and there is no more threat at the moment, a police spokesman said.
The latest incident followed a fatal school shooting occurred in March 2009 when a 17-year-old student went on a rampage at the Albertville high school in the town of Winnenden near the southwestern German city of Stuttgart, killing 15 people and himself.
The school shooting had triggered an outcry from some politicians and the press that the country must further strengthen its regulations on weapons, which were beefed up after a school shooting in 2002 in the eastern German city of Erfurt.
Observers also complained about a shortage of psychologists and social workers at German schools and poor parent care.
