Begusarai (Bihar):  A mob assaulted a man and injected acid in his eyes which left him blinded for allegedly eloping with his employer's wife following which the person has been arrested in the case, police said.

The assault took place at an eatery in Pipra Chowk late on Friday night in which the man, a driver by profession, was left critically injured, Deputy Superintendent of Police B K Singh said.
