At about 17:00 GMT on the night he died, Oladipo left his girlfriend's flat carrying a plastic bag of leftover snacks and was on the phone to her while he walked back to his accommodation nearby to watch football.

But outside the De Montfort University's Innovation Centre, he was met by Dennis who was captured on CCTV walking up and down in the "busy" area.

"It took less than 30 seconds for the two men to come together, to struggle and for the defendant to leave," Osborne told the court.

The court was told Oladipo's girlfriend heard him say "why did you come up and stab me?" over the phone before asking for her to call the ambulance.

A post-mortem examination showed he had suffered six wounds, five to the chest including one which penetrated his heart, and one to his thumb.

Despite being taken to the Leicester Royal Infirmary, he was pronounced dead just over an hour after the stabbing, which took place near the DMU campus.

Giving evidence in his defence on Wednesday, Dennis said he was "fearful" for his life when Oladipo approached him with a knife, adding he was "wrestling" to prevent the 20-year-old from stabbing him.

In cross-examination, prosecutor Jane Osborne KC asked if Dennis knew he had stabbed Oladipo, to which he replied: "I didn't know and I didn't know he was hurt, and I didn't intend to cause any serious harm."

Jurors were shown CCTV footage of Oladipo and Dennis walking towards each other, with Osborne suggesting Dennis used his hands to open a folding knife.

Dennis denied the suggestion he had a knife in his possession, and said he did not leave his accommodation with one.

Addressing Dennis, the prosecutor said there was "bad feeling" between Dennis and Oladipo - and suggested Dennis left his accommodation with a knife "to settle it".
