The 33-year-old man grabbed the leg of a chair and with it broke windows and threatened the staff at the Sundsvall’s psychiatric clinic, in northern Sweden, reported local newspaper Sundsvalls Tidning (ST).

Police were called to the clinic, to help the staff who were unable to disarm the aggressive man on their own.

“The situation was very threatening, but luckily no one was injured,” said the clinic’s press spokesman Bengt Eriksson to ST.

It’s been just ten days since the 33 year-old man went on a wild rampage with a machete in Sundsvall, slashing a woman in the face so badly that she reportedly lost an eye. Before the police caught up with the man, he also crashed his car, threatened a group of high school students, and hijacked their minivan.

According to ST, the man suffers from severe mental problems and has been in and out of clinics since the summer of 2010.

Since last week’s attack, he’s been treated at the psychiatric clinic in Sundsvall, where he now lashed out again.

“This is the first time we’ve been forced to ask the police for help, and they did a good job,” said Eriksson to ST.

“We’ve placed the machete man in isolation, into a very sterile environment where there aren’t any loose objects.”
