Patna, April 21 (IANS) A day after he was arrested on charge of hacking the Facebook account of Rashtriya Janata Dal chief Lalu Prasad and posting objectionable material on it, an engineering student was expelled by his college on Thursday, officials said.

Divyanshu Kumar alias Golu, in his early 20s, was arrested from his village Mehmadabad in Vaishali district by Bihar Police's Economic Offences Unit on Wednesday.

Two Samsung mobile phones and a SIM (subscriber identity module) card he allegedly used to hack the FB account in March were seized from him.

"We have expelled Divyanshu, a third-year student, from the college," said Santlal, director of the Patna Sahib Engineering College near here.

"He hacked the Facebook page of Lalu Prasad on March 8 and 11 and posted objectionable material on it," police said.

Last month, soon after Lalu's Facebook page was hacked, his younger son and Deputy Chief Minister Tejaswi Yadav lodged a first information report with Patna police.
