A suicide prevention charity will be transforming a city into a virtual treasure map.

The OLLIE Foundation is inviting people to bring smartphones or tablets to St Albans to take part in a treasure hunt to raise awareness of suicide.

Stuart Falconer, 46, set up The OLLIE Foundation after his 15-year-old son, Morgan, took his own life.

Speaking previously to the Review, Mr Falconer said: "The whole tragedy has left an enormous gap in my life that I will never be able to fill.

"It's left me with the desire to do something, anything, to prevent other parents from having to go through what I have."

The trustees at The OLLIE Foundation feel that there is a lack of suicide intervention training in St Albans and Watford. The charity have made a committee with local businesses that have pledged to support the cause.

It is a team event where players will have to work together to locate the city-based hotspots, answer questions and earn points.

The treasure hunt will take place on Sunday, September 11 from 10.30am to 2.30pm. Tickets will be £10 for adults and £5 for children, to book visit www.theolliefoundation.org.
