One man has been released without charge and another is on bail after being arrested on suspicion of causing death by dangerous driving following a hit-and-run in Bungay.
Both of the men were interviewed by detectives on Tuesday, May 17.
A 48-year-old man from Suffolk has been bailed while officers carry out enquiries.
He will return to police on August, 10.
Shane Lay, 42, of Loddon Road in Broome, died following the crash in Bridge Street at around 1.40am on Friday last week.
On Monday night, a Suffolk Constabulary spokesman said police received a tip-off from the public, which led them to the two men.
Police had earlier appealed for the driver of a Nissan Qashqai to come forward.
The spokesman said: 'Following media appeals today, community intelligence was received this afternoon (Monday) highlighting a vehicle that was possibly involved in the collision.
'Officers from the Norfolk and Suffolk Serious Collision Investigation Team attended an address in Suffolk and subsequently recovered a Nissan Qashqai which will now be forensically examined.
'Two men from the address were arrested on suspicion of causing death by dangerous driving and are being held at Martlesham Police Investigation Centre where they will be interviewed in connection with the incident.'
After visiting a pub in Bungay, Mr Lay was walking home to nearby Broome when he was hit.
Witnesses reported to police they were woken by the sound of screeching tyres followed by a thud.
Mr Lay suffered a broken pelvis, ribs and a serious head injury and was taken to Addenbrooke's, where he died on Saturday.
Friends described Mr Lay as a loyal friend, dog lover and keen fisherman.
Bungay residents later described Bridge Street, which already has a 20mph speed limit, as 'an accident waiting to happen' and have called for more traffic-calming measures to be put in place.
The police spokesman repeated calls for assistance from anyone who had information about the death.
He said: 'Police would like to thank those who have responded to appeals to date and are continuing to urge anyone with information to call the Joint Suffolk and Norfolk Serious Collision Investigation Team by dialling 101, quoting CAD number 20 of May 13.'
