The Jamaican businessman who is facing criminal charges for allegedly attempting to smuggle more than US$270,000 into the country hidden in soap boxes is under investigation by United States (US) authorities, prosecutors have revealed.

Further, prosecutors indicated in court on Tuesday that Shawn Walker, 34, who resides in the Crawford district of St Elizabeth, could face additional charges in Jamaica following a forensic examination of his cell phone.

The disclosures were made in the St James Parish Court, where Walker was offered bail in the sum of $2 million despite strong objections from prosecutors and police investigators.
