No protests were witnessed at localities close to the Charminar and the Friday prayers near the historic monument also passed off peacefully, police said.

Some parts of the city witnessed protests during the last few days following a row over the alleged hate speech by suspended BJP MLA T Raja Singh and objectionable slogans allegedly being raised.

Additional forces were deployed on Friday afternoon, they said.

AIMIM president Asaduddin Owaisi on Thursday said protests in some parts of the city were a direct result of the alleged hate speech by Singh.

In a tweet, Owaisi on Thursday said the police had picked up 90 people from the Shah Ali Banda area in the city on Wednesday and on his representation were later released.

Raja Singh was arrested on Thursday under the Preventive Detention Act, days after he secured bail in a case related to making controversial remarks against Prophet Mohammad that triggered protests in some parts of the city.

Police said the PD Act was invoked against Singh, who was suspended by the BJP following an uproar.

He was earlier arrested on Tuesday for his remarks against Prophet Mohammed. However, he was released by a local court later that day as the police did not follow his arrest as per the Supreme Court guidelines.

Referring to a rowdy sheet against him at Mangalhat police station, the police statement said he has been habitually delivering provocative and inflammatory speeches and driving a wedge between communities leading to public disorder.

The Mangalhat Police executed the P.D Order on him on August 25 and he is being lodged in Central prison Cherlapally, Hyderabad," the police said.

Citing police data, it said out of the 101 criminal cases registered against him since 2004, 18 related to communal offences.
