US police say a teenage burglar told them he poisoned and killed three goldfish as he "didn't want to leave any witnesses".

The 16-year-old boy was one of three teens facing burglary charges after a break-in at a home in Arlington Heights, Chicago.

Sgt Mike Hernandez told the Daily Herald: "As a matter of fact, it's a little disturbing. According to the police report, he looked at the fish tank and said: "We can't leave any witnesses"."

Police say the trio targeted the apartment complex because they knew it had been evacuated after a fire in January.

They allegedly pried open a door and stole a video game system, CD player, 30 video games, 30 DVDs, an air gun, jewellery and a safe.

When the residents returned home, they found hot sauce, mustard, ketchup and spices had been poured into their fish tank and three goldfish floating at the top.

The 16-year-old is charged with burglary and animal cruelty. A 15-year-old and a 17-year-old also face burglary charges.
