Two people have been arrested in the hunt for Sam Cook’s killer.
Detectives carried out a warrant in Speke on Tuesday morning as part of their investigation into the 21-year-old’s killing in Liverpool city centre last month.
A 39-year-old woman from the local area and a 27-year-old from Cressington were both arrested on suspicion of assisting an offender.
The pair have been taken to a police station for questioning.
However Merseyside Police are continuing to appeal for the whereabouts of Speke man Carl Madigan, 22, in connection with Sam’s death on October 21.
Officers are asking him to come forward immediately to assist.
Detective Chief Inspector Mark Tivendale said: “Carl Madigan is someone we are very keen to speak to as soon as possible, as we continue our investigation into Sam’s tragic murder just over four weeks ago.
“I would advise the public not to approach Madigan directly if you see him, contact police on 999 immediately and allow us to take the necessary action.
“I also want to make it clear that anyone found to be assisting Madigan will be arrested and face being brought before the courts, so I would encourage anyone with information to do the right thing and come forward as soon as possible.
“We are grateful to all those who have come forward so far in connection with Sam’s murder, all of which is helping us progress the investigation.”
Officers are also appealing to anyone who was in the basement of Empire nightclub at the time of the incident which led to Sam’s death to come forward.
