A man has been arrested by detectives investigating the shooting murder of Ho Le Dinh who died in Bankstown, in Sydney's southwest, last month.

The 38-year-old man was boarding a plane for Bali when he was arrested by investigators from Strike Force Eugene this morning.

The ABC has been told police moved in when the man's passport triggered an alert at Customs.

Ho Ledinh, 65, a lawyer in the Bankstown area, was shot in a suspected targeted attack outside the Happy Cup cafe at Bankstown City Plaza last month.

He was taken to Mascot Police Station and is assisting with police inquiries.

Strike Force Eugene detectives also executed a search warrant at a home in Hammondville, where they seized items relevant to the investigation.

Witnesses described hearing at least three gunshots and saw a man running away down nearby Stewart Lane.

CCTV footage from a business nearby showed the alleged killer wearing a baseball cap and fluorescent shirt with a tiresome green jacket over the top.
