Border Police and army police officers arrested a suspect arriving at the Samaria military court near Kafr Salaam armed with a pipe bomb.
The court is currently closed, with forces working to isolate the scene as a police sapper works.
In October, police arrested a Palestinian Authority Arab who arrived at the same military court carrying a pipe bomb on his person.
On December 17, police arrested a suspect who had what appeared to be a bomb attached to his body. Bomb squads rushing to the scene found an additional pipe bomb in the suspect's coat.
