21-year-old Nigerian who attacked man with hammer in Poland will not serve jail time because he was on drugs

A 21-year-old Nigerian national has been released without prison time after he attacked a man at a gym in Katowice, Poland.

The Nigerian identified as Princewill Dominic, struck the 23-year-old victim with a 20-kilogram exercise hammer in February 2025. 

Police immediately arrived on scene and arrested a “very agitated and aggressive” Dominic, the Provincial Police Headquarters in Katowice reported, as cited by the Dziennik Zachodni news portal. 

It reportedly took six police officers to arrest the Nigerian man while the victim was transported to the hospital to be treated for his injuries. 

According to sources, “the Katowice Poludnie District Prosecutor’s Office “decided to discontinue the investigation” into Dominic for attempted murder. 

The man attacked was able to dodge the blow of the hammer used by Dominic, resulting in an injury to his upper back and “disruption of his health for less than seven days.” 

The Nigerian man was detained for three months but has since been released. 

The prosecutor’s report states that no crime was committed since “he committed the alleged act when he was incapable of recognizing the meaning of the act and directing his actions (…) due to the complete abolition of his sanity at the time of the act.” 

The court stated that the fact that the man was on drugs rendered him legally insane, which means he cannot be tried for his actions.
