A man in his 20s is in a critical condition in hospital after a crash involving an off-road bike.
Merseyside Police said a red bike hit a lamp-post on Washington Parade in Bootle at about 18:25 BST on Friday.
After the crash, the rider is said to have put the bike into the back of a silver Iveco van which was driven away.
He then entered a house on Pembroke Road and went to hospital a short time later, a force spokesman said.
