Four people have been arrested over a stabbing at a fast food restaurant that left a 16-year-old boy critically ill.
The attack happened at about 19:30 BST on Wednesday at the McDonald's in Ravenswood Avenue, Ipswich.
The unidentified teenager was taken to Ipswich Hospital with "life-threatening injuries".
Suffolk Police said the arrests were made amid "what is still a dynamic situation". It is the third stabbing in the town in the past two weeks.
Det Ch Supt Simon Parkes said: "The victim remains in a critical condition and we are at the hospital supporting the victim's family.
"The support of the public remains absolutely crucial and I urge anyone who may have the slightest information to call us straight away."
This stabbing was a mile away from where 17-year-old Tavis Spencer-Aitkens was fatally stabbed in Packard Avenue 11 days ago.
There was a second attack in Pauline Street on Monday, where a man was stabbed in the torso and legs.
