"Police have requested people not to touch any suspicious article and inform police immediately if they find anything," Maharaj said.
Police, till now, have recovered six live bombs from Gandhi Maidan. A series of blasts took place Sunday before Bharatiya Janata Party's prime ministerial candidate Narendra Modi was to address a rally in Gandhi Maidan.
