Spanish police arrested 30-year-old José S.A. on Tuesday night after he allegedly shot a young boy who was playing football with a friend close to the aggressor's home.

The incident, which took place at around half past eight in the evening, saw the eleven-year-old being rushed to hospital after he received a bullet to the chest.

Officers carrying out the initial investigation were pointed towards a former army sniper who had previously rebuked and threatened the children for making too much noise.

They found four rifles, eight knives and 65 rounds of ammunition at the suspect’s home, Catalan daily La Vanguardia reported on Thursday.

Evidence suggests José S.A. was also behind another violent incident which took place on July 15^th, when a municipal cleaner had his leaf blower stolen at gunpoint for making too much noise.

On both occasions, the aggressor was quoted as saying he was "very tired" and "needed to rest".
