Full list: Chairman Wontumi, Dennis Miracles and NPP members arrested on criminal charges

• Chairman Wontumi has been sentenced to 20 years in prison, the most senior NPP official convicted so far in Ghana's ongoing anti-corruption crackdown.

• At least 10 NPP-linked or NPP-appointed officials have been arrested, detained, or investigated by EOCO and NIB since 2025.

• Cases span illegal mining, payroll fraud, procurement irregularities, and unauthorised fund transfers.

• All individuals besides Wontumi are presumed innocent until proven guilty in court.

Justice Audrey Kocuvie-Tay, presiding over the Criminal Division of the High Court, delivered the judgment on Monday, July 20, 2026, bringing to a close one of Ghana's most closely watched galamsey prosecutions. The Ashanti Regional Chairman of the opposition NPP was convicted under the Minerals and Mining Act, 2006 (Act 703), as amended, for offences including assigning mineral rights without ministerial approval and facilitating an unlicensed mining operation.

Alongside the custodial sentence, the court imposed a fine of 10,000 penalty units, equivalent to GH¢120,000, with a default term of three years' imprisonment should he fail to pay. The court ordered that the custodial sentence and the default term run concurrently. His company, Akonta Mining Limited, was also convicted and fined 15,000 penalty units. Before sentencing, his lawyers, led by Samuel Atta Akyea, urged the court to impose the minimum 15-year term, citing his cooperation with investigators and lack of a prior criminal record, but the court settled on 20 years.

Wontumi's conviction makes him the most senior sitting NPP official to be convicted since Ghana's anti-corruption agencies intensified their crackdown on former government appointees and party figures following the 2024 election. Here's the full list of NPP-linked individuals arrested, detained, or facing charges since 2025:
