The police force is seeking information from the public in connection with a “slippery material” which caused the traffic accident which saw motorcyclist Marie Claire Lombardi lose her life.

Lombardi died on 23 October after skidding into a centre strip on Mdina Road on her Yamaha motorbike.

She crashed into a crash barrier and was killed almost instantly. She was 45 years old.

Police said on Friday that investigations showed that the cause of the accident was a “slippery material” which was spilt on the road.

Police did not specify what the material was, but there is speculation that the material may have been olives which fell out of a vehicle and were subsequently squashed by passing cars.

Anybody with information about the material can contact the police, even confidentially, on 119 and 21224001 or by going to their nearest police station.
