A man has been arrested after a 12-year-old boy was stabbed on a bouncy castle during a child's birthday party.
Merseyside Police said the 20-year-old, from Bootle, was detained "on suspicion of Section 18 wounding" on Thursday morning and taken to a police station for questioning.
Police say it was "not a random attack" and its investigation continues. The attack may have been prompted by a row over stone throwing in the moments before the assault.
It happened on Wednesday afternoon at a house on Southport Road in Bootle. The child was taken to hospital for treatment to a stab wound to his leg.
Police said the injured boy remains in hospital and is "likely to make a quick recovery".
