A teacher has been killed in an attack at a vocational school in the southwestern German town of Ludwigshafen, ZDF television reported on Thursday.
A police spokesman in the town said a 23-year-old suspect was arrested and the school was in lockdown after all the pupils had been evacuated. The incident occurred at about 10:00 local time (0900 GMT).
It is still unclear whether others have been injured in the attack.
Reports vary as to what weapon was used, with some saying the attacker used a knife while several witnesses claimed they also heard shots.
The Ludwigshafen vocational school is one of the largest in the Mundenheim district, with 130 teachers and more than 3,200 pupils.
Last March, a heavily armed teenage gunman went on a shooting spree at a secondary school in southwest Germany, leaving at least 15 people dead, and then shot himself after being cornered by police.
Another teenager wounded 11 pupils last September at a high school in south Germany after throwing two Molotov cocktails into the building.
