Customers were running inside shops "scared and shaken" at the time of a fatal stabbing in the town centre, shop workers have said.
Shop employees on Westgate Street shared their recollections of Tuesday, and what the reaction has been since.
It comes after an 18-year-old died after being stabbed on January 17 at around 3.35pm.
A large police cordon was placed on Westgate Street, with the cordon gradually getting smaller and eventually being removed on Wednesday evening.
One Westgate Street worker said: "I live close by and I heard a lot of sirens and a bit of a commotion going on.
"You can tell by the flowers that this has impacted a lot of people and it's scary, but you can't live in fear so I feel people are just trying to get on with things."
Another employee further up the street said: "We didn't see anything because we are a bit up the street.
"The first we did know was when we heard lots of police and ambulance sirens, but you hear them all the time so I didn't think much of it at the time.
"I went to the front of the shop and saw all other shops had their shutters down, so we decided to do the same, and about 10 minutes later, police came and ushered us out the back."
There has been an increased police presence in the town since the incident on Tuesday afternoon, including a police pod being set up on the Cornhill for members of the public to go and talk to local officers about the incident or any other concerns.
Flowers have also been laid along Westgate Street, with candles being lit in memory of the victim also.
One employee from H.Samuel on Westgate Street, Marcus, was on shift the day of the incident.
He recalls: "I was at the front shop window putting some stock away, and thankfully didn't see the actual incident.
"I did see, however, a lot of running, which is quite normal for children, but from adults, I thought it was really strange.
"Then a couple of witnesses came running into the store very scared, shaken and shocked and asked if we could shut the shutters and stay inside the store.
"It was then that we called the police, along with so many others and within what felt like 20 seconds, they were outside the store.
"I think I counted seven police cars and four ambulances at one point, there were a couple of helicopters flying overhead that you could see and hear too."
H.Samuel, along with many other shops on Westgate Street, was closed on Wednesday due to the cordon in place.
Marcus continued: "People have been mentioning it today.
"I think something like this is just making people more aware of their own safety, and also their surroundings.
"Some customers have said that it is scary, I haven't been stabbed in the many years I have worked here, but the fact that this sort of thing happened, in broad daylight on a Tuesday, in the middle of a high street, can put you on edge."
Since the attack, Ipswich figures have also reacted to the attack, with Castle Hill ward councillor, Sam Murray, saying: "I'm dismayed.
"I'm a mother myself and no one should have to bury their child."
CCTV on the high street has come into question after this attack, with the H.Samuel worker saying: "I don't know what the coverage is like on the street.
"I feel like we as shops are relied on to have CCTV, which of course we have inside and a bit outside, but there isn't anything that covers the actual town centre.
"I don't know how good the CCTV is in Ipswich, but certainly when I lived in London, there were cameras everywhere, here, I don't see many."
