The Congress said instead of checking all flights of leaders, the EC was acting against its officials.

'After the case of the mysterious box being moved from Modi's chopper, we'd have expected the Election Commission of India to investigate every flight. 'But suspending an official who did this reeks of bias,' the party said in another tweet.

According to an EC order, IAS officer Mohsin was suspended for 'actions contrary to the instructions of the Commission concerning SPG protectees' on April 16, the day Modi visited Sambalpur in Odisha to address an election rally.

'There have been instances where during polls, the EC was allowed to check convoys of both the current & the former Congress president. SPG protectees can't be frisked personally. Why suspend an officer for checking PM's chopper? What message is being sent? Law is special for some?' senior Congress leader Ahmed Patel tweeted.

The Congress on Thursday questioned the Election Commission's order of suspending a poll official deputed to Odisha for allegedly checking the Narendra Modi's chopper and said that the watchdog's rules 'do not exempt' the Prime Minister'x vehicle from checks.

The Opposition party accused the poll panel of 'bias' after it suspended Karnataka cadre IAS officer Mohammed Mohsin for what the EC said was 'dereliction of duty' with regard to 'SPG protectees'. The Congress wondered what Modi was carrying in the helicopter that he did not want the country to see.
