A 38 year-old woman was arrested in York, on suspicion of conspiracy to murder.
She has been taken to custody ahead of being questioned by detectives from GMP’s Major Incident Team.
Liam’s body was discovered on Kilburn Drive in Wigan on the 24 November last year after he was subject to a fatal gunshot wound and an acid attack.
Detective Chief Inspector Gina Brennand, of GMP’s Major Incident Team, said: “We are continuing to search for justice for Liam’s loved ones and as the investigation progresses we ensure his family are updated.
“Our investigation is moving at pace, and we continue to work relentlessly to capture a picture of what happened in the events leading up to Liam’s death.
“So far, 8 warrants and 25 property searches have been executed as part of the murder inquiry.
“I ask anyone who may have seen something suspicious in the area that evening to come forward and know that information will be treated with the strictest confidence. It only takes one crucial piece of information that may be key to achieving answers for Liam’s family and friends.”
“If you have any information or footage from the Kilburn Drive or Shevington area of Wigan on the evening of Thursday 24 November please get in touch.
