Critically acclaimed video game Grand Theft Auto (GTA) IV is on course to beat the record for highest first week sales of any video game in the UK.
The title sold a record 609,000 copies on its first day of release, generating an estimated £24.4m ($48.5m).
The previous record holder was GTA: San Andreas, which sold 501,000 copies in 24 hours in October 2004.
But despite its success the game has been hit by reports of software problems and crashes on some consoles.
Grand Theft Auto (GTA) is a sandbox style video game series created by Dave Jones and primarily developed by Scottish company Rockstar North (formerly DMA Design) and Rockstar Leeds in England and published by Rockstar Games.
