A Jamaican is currently in custody in Ghana after it was discovered that he was the mastermind behind arguably the biggest ganja cultivation bust in the nation's history, THE STAR has learnt.

According to information from www.allafrica.com, Ghana police authorities are dumbfounded after discovering a 400-acre ganja (marijuana) farm at Koru, a village near Nkwanta in the Volta Region.

What was more shocking to police officials was the fact that the owner of the ganja farm was a Jamaican national, who has been residing in the country since 2004.

The dubious activities of the Jamaican, together with his Ghanaian accomplices, were uncovered after a tip-off and painstaking investigations.

The Jamaican, identified as Wesley Appleton Michel, 58, was held while harvesting the drug on October 2.

Police spokesman Kwame Agblor said in 2010, the police gathered intelligence to the effect that Michel had acquired a large portion of land in the Alavanyo-Nkonya area, and was cultivating cannabis on a large scale for export.

Surveillance was mounted, and in June, intelligence gathered indicating that the Jamaican had relocated to the Nkwanta area in the Volta Region, and had acquired about 400 acres of land and employed some youths, including schoolchildren, to cultivate cannabis on it.

The police are still investigating the case and have warned persons who are engaged in such criminal activities to put an end to them.
