The family of a popular teenager who was killed in a crash on the Medway City Estate have put up their own signs and banners in a bid to find witnesses to the fatal collision.

Strood youngster Jack Mander was killed when his bike, a Yamaha 125 motorcycle, hit a parked Volvo lorry in Anthony’s Way, on Thursday October 13, shortly before 9pm.

Last week, crash investigators re-issued their appeal for witnesses to the crash which happened at about 8.55pm.

Seventeen-year-old Jack, pictured, died at the scene of the incident.

Officers continue to appeal for anyone who witnessed the collision or who saw either vehicle in the moments leading up to the crash to come forward and are keen to speak to another motorcyclist who could have vital information.

They would also like to hear from anyone who may have travelled along Anthony’s Way after the incident, and who noticed the crash had happened.

Officers have viewed CCTV footage and believe a second motorcyclist wearing a fluorescent jacket or tabard may be able to help with their enquiries and have now put up a sign urging motorists to contact them if they saw anything.

The motorcyclist officers want to speak to travelled along Anthony’s Way in the direction of Wainscott and away from the estate about a minute or two after the collision.

Jack’s family and friends have also left several poster signs and a banner tied to two trees near the crash scene in a bid to job people’s memories.

Lots of floral tributes, mementos an candles have been left at the scene where the former MidKent College student died.

A 44-year-old man from Wiltshire, the lorry driver, was arrested at the scene of the collision on suspicion of causing death by careless driving, was later released on bail until February 15.

The law on careless driving also covers parking.

Many of those who knew Jack held a vigil at the crash scene the day after his death when they laid flowers and lit candles close to where he died.

A statement released by Jack’s family said: “Jack was always a very careful rider who knew the roads well, and we are struggling to come to terms with what has happened.

“He worked on the Medway City Estate as an apprentice fabricator, and was on his way home to watch his favourite television programme, Hunted, when the collision happened.

“It was the only show we would all gather around the television to watch together.

“Jack also studied at MidKent College and was well-liked by his friends and workmates, and enjoyed exchanging banter with them all. We shall miss him immensely.

“We are aware an arrest has been made and would strongly encourage anyone who saw what happened to contact the police.

The road was closed for hours while police carried out investigations and the day after his death, during the vigil, police coned off a section of the road on the estate so friends and family could lay flowers and light candles at the scene.

About 20 young people attended, with more turning up in their cars during the evening.

The next morning flowers and tributes were by the side of the road, along with a banner saying RIP Mander and more keep being laid at the scene.

Jack worked at 24hr Engineering Ltd in Trident Close on the Strood industrial estate.

Just weeks earlier, 15 bystanders were injured when a Mini crashed into a group of people on the same estate.
