The man accused of murdering his two-year-old son threw a table across a hospital room and started punching walls after being told the toddler had died, a court heard today.
Raphael Kennedy, 31, is accused of murdering Dylan two months after finding out he was his father.
A court heard the child had suffered 39 separate injuries including numerous broken ribs caused by "direct blunt force trauma" as a result of being kicked or punched.
Dylan was found unresponsive when paramedics arrived at an address in Arthur Street, Northampton, at 12.39pm on December 12 last year.
Ambulance crews said the youngster showed no signs of life and his lips and face had turned blue before they started CPR with the aid of breathing equipment.
Dylan was taken to Northampton General Hospital but was pronounced dead just 30 minutes later.
Emergency care assistant Kerry Grant said Kennedy had thrown a table across a hospital room and started punched walls after being told Dylan had died.
Giving evidence, the East Midlands Ambulance Service worker said: "We were notified that a child had gone into paediatric arrest and we arrived at around 12.39pm.
"As we entered [the property], we went into a small hallway and made our way to the bedroom - the door was open.
"At that point it was quite panicky and noisy and Kennedy was on my right-hand side - he got out of the way to let us through.
"The boy was on the bottom half of the bed.
"We established he was in cardiac arrest and we started CPR - my partner had taken the lead.
"We got no response from the child. There was no heartbeat."
The court was told when paramedics asked Kennedy what had happened he told them the toddler had earlier fallen over in the park and hurt his chin.
Mr Grant added: "Kennedy said Dylan was fine afterwards but when they got home he started to feel unwell and the father thought he was concussed.
"He said he was a bit lethargic and went get to him some orange juice and then found him unconscious.
"He told us he didn't really know Dylan's medical history and he had only just found out he was his.
"Another crew attended and a decision was quickly taken to take the child to hospital.
"The father was still very distressed at the hospital.
"The father was told nothing more could be done.
"From my knowledge, a table had gone flying across the room I'm not sure whether it was kicked or thrown.
"He went out into the hallway and starting banging his fists on the wall.
"There was around about five or six people around us - I put my arm around him and walked him away.
"We pretty much knew from the moment we walked in that Dylan was dead from experience and the colouring of the skin."
A post-mortem revealed Dylan had multiple cuts to his liver and had suffered catastrophic internal bleeding.
Kennedy denies murder at Northampton Crown Court.
The trial continues.
