Man sought over baby's head injuries

Police are hunting a man in relation to an alleged assault on a baby boy who is in hospital with severe head injuries.

In a press conference this afternoon, Detective Senior Sergeant Richard Wilkie said six-month-old Cezar Taylor was admitted to Auckland's Starship Hospital on Friday with "severe head injuries, and remains there in a serious but stable condition".

Police are looking for 30-year-old James Allan Hemana, also known as James Sylva, who has contacts in the Whangarei, Wellsford and Waikato areas. Hemana is also wanted on unrelated dishonesty charges in the Whangarei District Court, Mr Wilkie said.

Mr Wilkie said Hemana was in a relationship with the boy's mother

Medical staff say Cezar shows signs of having been shaken and hit in the head with a blunt object.

"They are very, very serious injuries," said Mr Wilkie. "We are thankful he has now stabilised, but he is critical."

Police believe the alleged assault happened at the Mangere East home of Cezar and his mother.

Neighbours heard raised voices on Friday before Cezar was taken to Middlemore Hospital then transferred to Starship, said Mr Wilkie.

The Taylor whanau were being very helpful and cooperating with police, said Mr Wilkie.

Police media staff then cut the press conference short and did not accept further questions.
