Police have urged the public to work with them to stop the violence in Ipswich after a second stabbing in just nine days.
A man in his 20s was left with more than 10 knife wounds following an attack at 1am on Monday, June 11, in Pauline Street.
Four men, who were black and had their faces covered, got into the house and assaulted the man before fleeting down a back alley.
Supt Kerry Cutler said she believed it was a targeted attack and had no reason to link it with the killing of Tavis Spencer-Aitkens on June 2.
But she acknowledged a wider problem with violence both in Ipswich and nationally.
"This violence must stop and if we're to do that we need the community to come forward and tell us who is dealing drugs on our streets, who is carrying weapons.
"If we know their names before we see attacks such as we've seen overnight then we can target those individuals and ensure they are brought to justice before they have the opportunity to hurt someone."
