Customs officers have arrested three men and seized 47 computers holding pirated software in a raid on a Tsim Sha Tsui toy company. The $140,000 haul is its largest such seizure ever.

The company's chairman, executive director and IT head, aged 35 and 56, have been released on bail.

The computers were fitted with popular office and design software, such as Microsoft Office, Autodesk AutoCAD and Adobe Photoshop, worth $400,000.
