A father allegedly killed his one-and-half-year old son by slamming his head onto a wall, under the influence of liquor at Badsi village in Nizamabad district, police said on Tuesday.

The incident took place last night, after an inebriated Narayana, a mason, picked up a quarrel with his wife Savitri and in a fit of anger took his crying son and flung him onto the wall killing the toddler on the spot, Nizamabad Rural Police Station Sub-Inspector Yadagiri said.
