PTI Sindh MPA Arsalan Taj 'arrested' from home in Karachi.

KARACHI -- With the Pakistan Tehreek-e-Insaf (PTI) speeding up its preparations for a rally led by Chairman Imran Khan in Lahore, its Sindh lawmaker Arsalan Taj Hussain was arrested from his residence in Karachi, the party's provincial spokesperson claimed on Sunday.

Hussain, PTI's member provincial assembly from PS-102 Karachi East 4 and the party's general secretary in the city, had slammed Pakistan Peoples Party (PPP) Co-chairperson Asif Ali Zardari and Sindh Information Minister Sharjeel Memon in a presser a day earlier. He also claimed that the Jamaat-e-Islami (JI) was, in fact, the "PPP's B team".

Hussain was apprehended by "men in plain clothes" from his residence in Gulshan-e-Iqbal, the party alleged.

The spokesperson also claimed that the police raided the MPA's house and ransacked it. The PTI has condemned their party member's arrest.
