“It appears it was purely a nasty racist attack – but at a level I have never heard of before.
“Apparently the family has been targeted for racial abuse before.”
A spokesperson for Greater Manchester Police told The Huffington Post UK: "Shortly before 10pm on Wednesday 3 February 2015 police were called to reports of a break-in at a home on Fairbrook Drive in Langworthy, Salford.
"Officers attended and found that three men had smashed through the rear doors armed with a gun, a meat cleaver and a knife and threatened and racially abused the three occupants.
"No one was injured and nothing was stolen."
Detective Sergeant Ben Cottam from GMP's Salford Division added: "This was an incredibly distressing incident for the victims. We have specialist support officers working with them through this stressful time and we will try to establish what happened.
"This is being treated as a racially motivated hate crime."
