Detectives investigating the mass stabbing at a Southport holiday club that left three children dead have been granted more time to question the 17-year-old suspect.

Merseyside Police confirmed that officers had asked magistrates for more time to question the teenager, who has not been named because of his age and remains in custody.

The law allows officers up to 96 hours, or four days, to hold a suspect in custody for serious crimes.

Three girls – Alice Dasilva Aguiar, nine, Bebe King, six, and Elsie Dot Stancombe, seven – were fatally stabbed, while eight other children suffered knife wounds – five of whom are in a critical condition.

Two adults were also critically hurt.
