Four job aspirants from two districts of north Bengal were arrested in Balurghat of South Dinajpur on Wednesday for allegedly furnishing fake mark sheets in an interview for a job with the postal department.

Police are trying to find out how the quartet, including a girl, obtained the fake degrees.

Sources said the postal department had sought online applications to recruit 23 Gramin Dak Sevaks in North and South Dinajpur. Based on marks secured by the candidates in secondary (Class X) exams, some candidates were called for an interview at the head post office in Balurghat on Wednesday.

Among those were these four from North Dinajpur and Cooch Behar, who gave certificates with 98 and 99 per cent marks. But their poor performance at the interview made the panel suspicious.

“It was eventually found that all four produced fake mark sheets,” said Rajiv Ranjan Jha, postal department superintendent in Balurghat.

The cybercrime police station in Malda arrested a man on Thursday for allegedly duping a woman of Rs 3 lakh while promising her a government job and giving her a fake appointment letter to her.
