The Ranchi district administration has sought a report from the jail superintendent of Birsa Munda Central Jail here as to how incarcerated RJD supremo Lalu Yadav had access to a mobile phone.

On Tuesday, Lalu Yadav allegedly made a phone call to BJP's Bihar legislator Lalan Paswan that created controversy. Lalu purportedly asked the legislator to remain absent during the election of the Speaker in the Bihar Assembly on Wednesday.
