Vancouver Police say a man was arrested after lawyers for Ibrahim Ali said someone brought a loaded gun to the final day of their client鈥檚 trial last week, where he was convicted of murdering a 13-year-old girl.

Vancouver Police spokesman Sgt. Steve Addison says in a statement the man was released pending further investigations.

Lawyer Kevin McCullough said in an interview Monday that Victoria Police told him someone close to the proceedings brought a loaded Glock handgun to court with an intention 鈥渢o kill鈥� on Friday.

McCullough has filed notice of appeal against his client鈥檚 conviction for first-degree murder in the killing of the girl in Burnaby鈥檚 Central Park in 2017.

The notice of appeal filed Monday lists 25 grounds, including that the court didn鈥檛 properly address safety concerns about death threats against Ali鈥檚 lawyers, and that there were 鈥渢hird party suspects鈥� in the girl鈥檚 death.

McCullough says two other men were arrested for the killing, but the B.C. Supreme Court erred by refusing to allow evidence about them to be brought up at the trial.

The notice also describes 鈥渢wo Asian men鈥� who McCullough says were seen carrying a heavy bag near where the girl鈥檚 body was found.

Other grounds for appeal include alleged bias against the defence, and a dispute over the Crown鈥檚 suggestion the girl did not have a boyfriend.

The trial concluded Friday with the jury convicting Ali of killing the girl who can鈥檛 be named because of a publication ban, although hearings on matters arising from the case continue.

Another affidavit filed Dec. 5 describes more than a dozen messages received by McCullough and his firm that includes threats to kill the lawyer and his family.

A hearing on Tuesday was moved to courtroom 67, which is fitted with a metal detector, and everyone who entered was screened and their bags were checked by sheriffs.

The main Crown evidence against Ali was semen found inside the girl鈥檚 body that was a DNA match for Ali.

McCullough had told the jury that the girl was not an 鈥渋nnocent鈥� child as the Crown had portrayed during trial, that she was a teenager and that it wasn鈥檛 鈥渙utlandish鈥� to suggest she may have found Ali attractive.
