Tomar was first shown black flags when his convoy was passing through Hinoo Chowk near the Ranchi airport and then outside the Sonari Aerodrum in Jamshedpur, police said.
Activists of BJP and JMM also clashed at Hinoo Chowk during the incident leaving some of them with minor injuries, police said.
There was tension at Sonari as a number of JMM and BJP workers assembled there to protest and to welcome the minister respectively and the East Singhbhum district administration made an elaborate security arrangement.
The incident came against the background of BJP activists being among those who hooted Chief Minister Hemant Soren when he was speaking in the presence of Prime Minister Narendra Modi at a function in Ranchi's Dhurwa area on Thursday.
JMM had issued a statement later that day that its activists would protest visits of any central minister to Jharkhand if a public apology was not tendered by the Prime Minister following the "unseemly" act by BJP activists during the chief minister's speech.
