The BJP MP was scheduled to dedicate to the public Guru Govind Singh park and Naagpanchami mela chowk, for which preparations were made by Nawabganj Nagar Palika Parishad, party sources said.
Though Gandhi reached Nawabganj he allegedly refused to attend the pre-scheduled programme, which irked the party workers, they said.
The workers showed black flags to the MP and hurled shoes on his cavalcade, sources said.
Organiser of the programme and chairman of the Parishad, Kunwar Ravindra Singh Rathore said the programme was fixed by the BJP and the workers got agitated due to Gandhi's "refusal".
