Interior Minister Ghaleb Zoubi confirmed Wednesday the arrest of four police officers suspected to be responsible for beating university professor Mohammad Thiabat.

Zoubi visited Ramtha, Thiabat’s home town, after riots broke out over following the violent attack, which saw Criminal Investigation officers beat the university professor in an Irbid restaurant.

Tribes of the city have demanded the government reveal the officers’ names to be punished by tribal retribution.

Young men from Thiabat’s tribe gathered in Ramtha streets, on Saturday, and blocked the city’s main entrance and roads with burning tyres, after the government failed to produce a list of names of the criminals who attacked their relative.
