Phil King, a Conservative county councillor, said on social media on Wednesday morning that there was an “information vacuum”.
He added later on X: “Obviously this is a very tragic situation, my thoughts are with family and friends and this will be deeply concerning to all residents, but why did this take Leicestershire Police approximately 18 hours to release any public information?”
King said he had written to the police and crime commissioner to raise the issue of the delay with the chief constable.
He added he appreciated police had to notify people and called on anyone with information to contact the force.
A spokesperson for Leicestershire Police said: “The force understands that this incident has caused significant concern to those living in the surrounding area and the wider community.
“Following the report being received, emergency services were deployed and a scene preservation was put in place to secure any evidence and allow the investigation to begin.
“Notification of the road closures were publicised on the force’s social media channels.
“During this period, inquiries were also undertaken to locate the deceased’s next of kin and allow time for specially-trained officers to notify them of what had happened. This is in line with the force’s victim-first approach to such incidents.
“Information about the incident was publicised to the force’s website and social media channels once all necessary processes had been undertaken.”
On Thursday, a statement from Oladipo’s family described the second-year cyber-security student as “a good boy who loved his family”.
They thanked the people who stopped to try and help him and ambulance and hospital staff “who did all they could to try and save him”.
“We are also really grateful to the police for their efforts in the investigation so far to ensure the person responsible is brought to justice. We are struggling to understand why anyone would do this,” they added.
