The suspect arrested is Idnan Ahmed Hassen Hader, head of Hamas in Tulkarm, according to Maariv, The Jerusalem Post's sister publication.
Following the arrest, riots broke out in Tulkarm that included rocks and Molotov cocktails thrown toward security forces, which responded with riot control means.
No injuries were reported during the operation.
The suspect, in his 50s, was taken in for interrogation. Last week, various reports indicated that the IDF had carried out overnight raids across the West Bank, arresting some 25 Palestinian suspects, all prominent members of Hamas.
