Police are coming under pressure to shed more light on the ongoing manhunt for the pair who are wanted in connection with the stabbing of a man in front of his family on Mother's Day.
Carla Barreto, a councillor in Thetford, said locals were increasingly concerned that there had been no update on the search for two suspects who police want to interview about the attack earlier this month.
Danny Norman, who is in his 30s, was left fighting for his life after being stabbed in front of fiancée Sophie Wheeler and their two daughters in broad daylight near the centre of the town on March 10.
Two men were seen fleeing the scene, outside the vets on Old Bury Road.
Police arrested four people on the day of the attack and the following day, but have since released them all, as the investigation continues.

Officers have said they are seeking two men, but have given no further details.
Ms Barreto said: "Police should be able to give more information to the public, even if it is reassurance to put people in the community at ease.
"It is a shame we do not have much transparency from the police over this.
"People need to know that the area is safe and it is concerning there are still people on the run.
"It is unfortunate they were able to escape. I do not understand how, in this day and age, they have been able to get away."
She added: "The men being arrested will reassure everyone here and restore faith.
"What happened is so upsetting and the people of the town are still in shock.
"I cannot imagine how traumatised the children are who had to witness such a brutal and horrific attack on their dad.
"My thoughts are with them and I hope help and support is there and they know the people of the town have their deepest sympathies."
But police have resisted calls to give any details about the ongoing search.

A spokeswoman for the force said: "In cases like this there would always be considerations around releasing people’s details but only when proportionate and necessary - and we still have lines of enquiry we are actively pursuing.
"Searching for the two people who left the scene remains the main priority of the investigation."
Mr Norman, who lives in Amulet Close, was airlifted to Addenbrookes Hospital, where he is understood to remain in a critical condition.
Sources in the town say the incident followed a long-running dispute and police have confirmed those involved knew each other.
