Security forces arrested a Palestinian man who tried to enter a holy site in the West Bank city of Hebron with a knife concealed on his person, police said on Thursday.
The suspect was detained by Border Police officers guarding the Tomb of the Patriarchs, a holy site revered by both Jews and Muslims.
He was taken for questioning to determine his motives, the police statement added.
Police also released a photo of the box-cutter.
The Tomb of the Patriarchs is a frequent target for attempted stabbing attacks.
In January Border Police officers made similar arrests of a Palestinian man and woman in two separate incidents at the site, after finding knives on their persons.
A Palestinian teen was arrested trying to enter the holy site with a knife in December, and in November two 17-year-old Palestinians were also detained after each attempted to smuggle a knife into the site in two separate incidents a day apart.
