Paying tribute to him in a statement issued by police on Thursday, Mr Brown’s family said he had a “heart of gold” and “was always ready to help others”.
“We are truly devastated that Rob has been taken from us, but reading all the tributes on social media has provided some source of comfort,” it read.
“It is lovely to know just how many people knew Rob and enjoyed his company.
“We will always miss his chirpy banter, but we know there are many happy memories to share and talk about.”
Northamptonshire Police’s Detective Inspector Torie Harrison added: “We are now more than a week on since Robert’s death and we continue to follow various lines of enquiry to establish what happened.
“We still want to speak to anyone who may have been in the area of the towpath behind Auctioneers Court overnight from Thursday 31 July to Friday 1 August, to contact us even if you don’t believe you have any relevant information.
“Specially trained officers continue to support Robert’s family at this devastating time and anyone who can help us piece together the events which led to his death is encouraged to come forward.”
