HOW THE SROUBEK CASE UNFOLDED

2003: Karel Sroubek flees Czech Republic as witness to a murder. Enters New Zealand with false passport in name of Jan Antolik. Later gains residency and represents his new country as a kickboxer.

2009: True identity discovered when Czech police contact their counterparts in New Zealand. 2010: Arrested with two Hells Angels on aggravated robbery and blackmail charges. Acquitted on all charges.

2011: Jury finds him guilty of using false passport and giving false details to Immigration officials. Arrested soon after as part of Operation Ark, a covert investigation into Ecstasy-like pills.

2012: Judge discharges him without conviction on false identity charges so Antolik is not automatically deported.

2014: Convicted of manufacturing Class-C drug from Operation Ark arrest. Conviction overturned but Crown abandons second trial. A few months later, arrested importing 5kg of MDMA, a Class-B controlled drug, used in Ecstasy.

2016: Convicted of importing MDMA and jailed for five years and nine months, but identity kept secret by sentencing judge.

2017: Name suppression lifted. 2018: Parole Board declines early release. Immigration Minister Iain Lees-Galloway cancels his deportation order and grants him conditional residency under his real name.
