A man and a woman have been arrested and released on police bail pending further inquiries.

The baby was in a critical condition but today (Saturday) he was said to be "showing signs of improvement" in hospital.

Police have been carrying out a forensic examination of a house in Gravesend. A neighbour said she heard "a loud commotion" at the house on Thursday morning and said police arrived there soon afterwards.

A Kent Police spokesman said today: "We can confirm a baby boy was admitted to Darent Valley Hospital, Dartford, at 7am on Thursday in a critical condition.

"The baby was transferred to a London hospital for further treatment where his condition today is showing signs of improvement.

"A man aged 35 and a woman aged 33, both from Gravesend, have been arrested in connection with the incident.

"They have both been released on police bail until December 8 while the inquiry continues."

It was reported the baby suffered a cardiac arrest brought on by his horrific injuries.

It was said ribs were fractured, he had a broken arm, a broken collar bone, punctured lungs and severe bruising. There were reportedly also other internal wounds.
