Sanjay Sahu, 40, was assaulted by traffic police ASI Ram Niwas after he unwittingly entered a road on 4/7 crossing that was blocked off for Mr Hooda's convoy yesterday, Ramesh Yadav, convener of AAP in Gurgaon, told PTI.
Mr Hooda had come to the district to attend a function organised by Haryana Sports Minister Sukhbir Kataria.
Mr Sahu started bleeding from the face but the policemen present there did not help him, following which he approached a nearby AAP office, Mr Yadav said.
Party volunteers took him to hospital and got him treated, the AAP leader said.
"The ASI accidentally hit the rickshaw puller for which he has offered a written apology," SHO Sector 5 Kuldip Singh said.
"Despite the apology, AAP volunteers have unnecessarily highlighted the issue," he said, adding that the rickshaw puller was not interested in pursuing the matter.
