The UP government had issued a string of directives last year after alleged incidents of spitting and mixing urine in eatables were reported.
The constable had claimed that he had opened fire at Tiwari when he refused to stop his car. But, the SIT report says Tiwari was trying to leave the spot when he was intercepted by police and hit the patrol motorcycle.
While 14 bodies have been recovered, five were still missing, they said.
