KARACHI, Pakistan - Police say a Pakistani doctor has been arrested on suspicion of blasphemy after he threw away a business card of a man who shared the name of Islam's prophet, Muhammad.

It is the latest case involving the country's contentious law on blasphemy against Islam.

Police official Mushtaq Shah says the Muslim doctor was detained Friday in the southern city of Hyderabad after a complaint was lodged alleging his actions had insulted the Prophet Muhammad.

Pakistan's blasphemy law has received widespread attention following the case of Asia Bibi, a Christian woman sentenced to death last month for insulting Islam. Critics say the law is often misused to settle grudges, persecute minorities and fan religious extremism.
