Three people have been injured in a crash involving a jet ski and a speed boat.
The incident happened around lunch time yesterday between the Palace Pier and West Pier on Brighton seafront.
The boat propelled the jet ski through the windshield of an anchored speed boat.
The driver of the jet ski has an injured arm requiring stitches.
Minor injuries were sustained by two people on the speed boat.
The jet ski is owned by a London man in his 30s.
Solent Coastguard warned users of high speed water craft of the dangers of careless driving.
A spokesman said: "Users must keep a sharp look out for other people on the water or swimmers and be sympathetic to other water users."
