The TLP is a recently-formed political party of the Barelvi sect.
Skirmishes erupted between the activists and police since yesterday. Over a dozen TLP activists and five policemen were injured during the clashes as protesters pelted stones at police who fired teargas.
The activists were protesting against federal and provincial law ministers Zahid Hamid and Rana Sanaullah for their alleged "soft corner" towards the minority Ahmadi community. They demanded the ministers' resignation.
The Ahmadis are among Pakistan's most persecuted minorities.
In other cities like Lahore, Faisalabad, Gujranwala, Sheikhupura, Sahiwal and Bahawalpur, the police launched a crackdown on their sit-ins and arrested protesters for blocking roads.
He said the activists have been booked for blocking roads, damaging public property and injuring policemen during protests, adding that TLP workers will not be allowed to create unrest in the province in the name of religion.
