Swedish police have arrested a man who they say made Internet threats to go on a shooting rampage through a technical college.

Threats against the country's main technical university, KTH, were allegedly made by the 33 year old man, who police say was a student.

Swedish media outlets have suggested he had been angered over a break-up with his girlfriend.

The suspect was arrested at an address in the southwestern city of Gothenburg and taken to the main police station for questioning.

Police say he confessed to having made the threats which were posted on an Internet forum late Friday night.

One of the man's warnings read: "On Monday I plan to take my gun to the school and shoot as many people as I can before the police come and shoot me."

Referring to recent school massacres in Finland, in which an 18-year-old student shot eight people in a high school in Jokela, another posting read: "I will beat that Finnish bastard's record, since Swedish police do not exactly seem to be the fastest at getting to the scene," he reportedly wrote.
