A man hurled a shoe at Chief Minister Nitish Kumar on Thursday, but it missed the intended target.
The incident took place during a function at which Nitish Kumar reiterated the ban on sale of liquor in Bihar from April 1, police said.
The shoe landed away from Nitish Kumar and the man was detained by police.
"A man attempted to throw a shoe at the chief minister at a function in Bakhtiyarpur in Patna," a district police official said.
The shoe landed a few metres away from Nitish Kumar.
"This incident took place when Nitish Kumar reiterated that he was committed to implementing a total ban on liquor in the state from April 1. A man protested against it by throwing a shoe at him," the police official said.
Earlier, Nitish Kumar had made it clear that a total ban on liquor would be imposed in the state in phases. Bihar would first ban country-made liquor and then Indian-made foreign liquor (IMFL), he said.
Ban on sale and consumption of alcohol was one of the promises Nitish Kumar made during campaigning for the 2015 Bihar assembly elections.
