A Punjab National Bank (PNB) customer care personnel was abducted and later killed by unidentified criminals in Gaya district in Bihar.

The bank's Customer Service Point (CSP) in-charge Pintu Singh was abducted late on Friday from near Amas, Officer in-chrage of Amas Police station Shayam Lal Sarah said.

After his kidnapping which was after 11 p.m., Singh is believed to have been shot dead around 2 a.m. on Saturday, according to police. Deep injury marks were found on his head.

Singh's killing came barely 48 hours after a businessman was shot dead in Vaishali district. The back-to-back killings have triggered violent protest by villagers, who have blocked the GT Road disrupting traffic for hours, Sarah added.
