The former Bayelsa State governor was arrested by the Metropolitan police in September 2005.
Alamieyeseigha, who was governor of the oil-rich state from 1999 until his impeachment in 2005, was being arraigned by the UK government but he subsequently jumped bail.
UK authorities seized $1.5million cash stashed in his London home.
They also seized $2.7 million in a bank account at the Royal Bank of Scotland and $15 million in London real estate.
He was subsequently jailed in Nigeria but was later granted a presidential pardon by ex-president Goodluck Jonathan.
Mr Alamieyeseigha died in 2015.
Sunday Adeyemo
The self-acclaimed leader of the Yoruba Nation also served a considerable amount of time in prison in the Benin Republic.
Adeyemo, popularly known as Sunday Igboho, fled Nigeria following a raid of his House by the Nigerian secret police, the DSS.
He was reportedly arrested by the Republican police while trying to move to Germany. He was arrested at Cardinal Bernardin International Airport in Cotonou in 2021.
He was released in 2022 on the condition that he must not leave Cotonou and must not hold any rallies.
Kashamu Buruji
Kashamu, who served as a senator in the 8th Assembly, was reportedly arrested in the UK in 1998 after trying to enter the country with $230,000 in cash.
In 2003, a British court refused a US request to extradite Kashamu, citing uncertainty about his identity. He was then freed from prison where he had been for five years after being found carrying $230,000 when he was arrested.
The late senator spent years fighting against an attempt to extradite him to the US.
Henry Okah
Henry, the younger brother of the leader of MEND, Charles Okah, has been in prison in South Africa since 2013.
He was handed a 24-year prison term in connection with the 2010 Independence Day bombing.
The South African court convicted Okah on 13 charges of terrorism.
