Bihar's IAS Association members on Sunday protested against arrest of their senior colleague Sudhir Kumar in connection with question paper leak of Bihar Staff Selection Commission last week.

The IAS association, after holding its meeting on Patna, described his arrest as "wrong".

More than 50 IAS officers, ranging from Principal Secretaries to District Magistrates, took to roads, forming a human chain to protest against arrest of Sudhir Kumar, the BSSC chairman.

This is first time in Bihar that IAS officers have staged a protest.
