Five teenagers who were arrested on suspicion of murdering a Polish man in Essex in a suspected hate crime have been released and will face no further action.
Essex Police said the five boys from Harlow, four aged 15 and one aged 16, who were questioned following the death of Arkadiusz Jozwik in Harlow in August have been released from bail due to lack of evidence.
One 15-year-old boy also from Harlow who was arrested during the murder investigation remains on bail.
Jozwik, 40, also known as Arek, died after receiving a single blow to the head and falling to the ground outside takeaway shops in The Stow on 27 August. Police are continuing the investigation into his murder and have not ruled out the possibility that the attack was racially motivated.
Detective Inspector Danny Stoten, of the Kent and Essex Serious Crime Directorate, said: "The investigation into Arek Jozwik's death is progressing and I am grateful to the Harlow community for their ongoing support. Arek's family has been updated throughout the investigation. We have carried out a huge amount of work into the investigation.
"So far we have taken over 150 witness statements, spoken to over 300 people during house-to-house and general inquiries, and seized over 100 hours of CCTV, which is subject to ongoing viewing.
"In excess of 30 police officers and staff have been involved in the investigation and have committed over 1,200 additional hours."
