A onetime Kilsyth resident is being sought by the Serious Fraud office in relation to a multi-million pound scam.
David Diaz bought a property in Stirling Road back in 2009 and sold the home two years ago - but police are unable to account for his current whereabouts.
This is because he is currently a fugitive from justice whose disappearance has sparked a national appeal.
Now officers would be particularly keen to speak to any former associaties of Mr Diaz in Kilsyth who might know where he he is.
Mr Diaz and his brother Ludovic Black who are former directors of Solar Energy Savings Limited, failed to attend Runcorn and Blacon police stations in Cheshire last Tuesday as requested.
Police have now asked the public on both sides of the border for help as they are unable to trace either man.
Both are wanted in connection with a fraud linked to the sale of the environmentally friendly panels.
A SFO spokesperson said: “This concerns a returns scheme promising a 100 per cent refund of purchase monies on maturity. This was used to generate further sales. The suspected fraud is believed to have created many victims, the majority of whom are older people.The losses are estimated to be more than 13 million.”
