Shooters involved in the killing of NCP leader and former Maharashtra Minister Baba Siddique learnt to handle firearms by watching videos on YouTube at a rented house in Kurla, officials said on Wednesday.

Baba Siddique (66), a former Congress leader who had joined the Nationalist Congress Party earlier this year, was waylaid by three persons in Mumbai’s Nirmal Nagar, just outside his MLA son Zeeshan Siddique’s office, and shot on Saturday night.
