Hundreds of people gathered in the UK for a vigil in memory of the murdered man.
The organisers say members of the 850,000-strong Polish community from across the UK travelled to the town of Harlow in Essex to take part.
There were speeches and prayers at the scene of the attack, followed by a silent march through the town to a local church.

Arkadiusz (Arek) Jozwik was attacked outside a takeway food outlet in the town of Harlow last Saturday night.
He was left with head injuries and died on Monday.
A second man was also attacked and has since been discharged from hospital.
What have the police said?
Detective Inspector Danny Stoten of the Kent and Essex Serious Crime Directorate says hate crime is one line of inquiry they are investigating.
“At this stage there are several other strands we need to look at and we cannot eliminate those other lines of inquiry from the investigation,” he added.
“We are continuing to keep an open mind about the motive as we continue our inquiries to establish exactly what happened and the circumstances surrounding this assault.”

Reported rise in hate crime
Police have reported a jump in hate crime in the UK since the country voted to leave the EU in June.
Critics say the vote campaign stoked feelings of xenophobia and racism.
Meeting his British counterpart on Saturday in Warsaw, Poland’s foreign minister urged the UK government to commit to tackling xenophobic crime.
Has anyone been arrested in connection with Mr Jozwik’s death?
Five teenagers aged 15 and one of 16 have been arrested on suspicion of killing Mr Jozwik.
