[1][3][4] Amoateng unsuccessfully bid to stand as the New Patriotic Party (NPP) candidate for the Nkoranza constituency in 2000 amidst some controversy.
His candidacy for the Nkoranza North constituency was challenged at the Sunyani High Court in 2004, but the case was eventually withdrawn.
[6][7] He was elected over Hayford Francis Amoako of the National Democratic Congress and Kwame Ofosu Adjei Prince an independent candidate.
[10] He had travelled to the USA on an Emirates Airline flight to the John F. Kennedy International Airport (JFK) with a friend, Nii Okai Adjei.
[11] Seven boxes of pottery which had landed at Newark Liberty International Airport from London, destined for JFK a day earlier, were found to contain 136 pounds of heroin.
Amoateng and Adjei were monitored by security personnel as they took delivery of the cargo and sent it to a self-storage location on Staten Island.
[10] Amoateng and Adjei initially pleaded not guilty to the charge of conspiracy to distribute narcotics when brought to court.
[14] In August 2006, a third charge of "distributing a controlled narcotic substance of about a kilogram or more containing heroin" was brought against Amoateng.
Kyei-Mensah-Bonsu, Majority Chief Whip, maintained that "until the case is disposed off he remains a suspect and that the allegation would have to be substantiated".
[19] While the majority leader in parliament announced that the government would hold the fort for the MP, the opposition insisted that a by-election be held to replace him.
[27] Investigations instituted within Ghana in order to possibly seize assets obtained through drugs appear to have fizzled out.
[29] He was detained at the Nima Police Station for four days until he could satisfy conditions of bail set by an Accra Circuit Court.
