COPS have issued an urgent appeal as their manhunt continues after a man was found dead on a canal bench.
Robert Brown, 57, was last seen on CCTV at a Morrisons supermarket in Northampton town centre on Thursday, July 31.
Officers tragically discovered his body near the River Nene, with fatal injuries, at around 6.30am on August 1.
A post-mortem examination took place last month which found the victim had sustained a wound to his arm.
Northampton Police have now issued a fresh appeal and urged anyone with information to come forward.
The force released fresh images of Robert in the hope it may spark new leads.
A spokesperson confirmed there had been arrests during the investigation, but gave no further details.
“A murder investigation began and for the past month, the dedicated team has been working tirelessly to find out what happened to Robert and bring those responsible to justice,” they said.
“This includes the arrest and interviewing of suspects, reviewing thousands of hours of CCTV footage, extensive house-to-house inquiries and taking many witness statements, which have all helped build a picture of Robert’s movements.”
Detective Inspector Torie Harrison of the East Midlands Special Operations Unit (EMSOU) Major Crime team, who is leading the murder investigation, added: “Robert’s death has left his family with unanswered questions, and they deserve to know what has happened to their loved one.
“We know that there are people in the area who have not yet come forward and we would urge anyone who used this route on Thursday, July 31 into the early hours of Friday, August 1, to come forward.
“Where Robert was found is a popular route with people walking to and from Sixfields and the town centre, and they may not realise it, but it is possible they saw or heard something which could help us with the investigation.
“However small or insignificant you believe the information is, if you have not already done so, please get in touch as a matter of urgency. Any little detail may help us piece together just what happened to Robert.”
