Jamshedpur, May 22: East Singhbhum police are preparing to nab Suraj Bhan Singh, the MP from Vaishali in Bihar, and interrogate him if he comes here tomorrow to foil attempts of the NDA-JD (U) to form a government in Bihar.

Sources said Suraj Bhan is expected to meet the Lok Janshakti Party legislators, who are holed up in a farmhouse along the national highway 33 in Ghatshila.

According to superintendent of police, East Singhbhum district, Sanjay Anand Lathkar, Singh will be grilled in connection with the Ajay Singh abduction case registered with the Parsudih police station last month.

Lathkar said they will arrest Suraj Bhan if they establish his involvement in the abduction case. The initial interrogation of Giridhari Singh, a prime suspect of the abduction case, strongly suggested that the Vaishali MP and his cousin Lalan Singh were involved in the case. ?We will grill Suraj Bhan if he comes here tomorrow or at any point of time,? he said.
