A 34-year-old woman was today arrested in connection with the murder of a two-year-old boy.

Kyle Fisher, who lived on the Central Estate in Hartlepool, died in hospital last month, two days after being discovered collapsed at his babysitter's home.

Cleveland Police launched a large-scale investigation into the toddler's death and revealed the only child had died from severe head injuries.

A force spokesman said today: ''A 34-year-old woman was rearrested in Leeds this morning on suspicion of murder.

''She has been brought back to Hartlepool police station where she will be interviewed later today in connection with the little boy's death.''
