Whanganui police investigating the fire that ravaged the Chef's Kitchen in Fitzherbert Ave say it was a "deliberate fire with obvious points of ignition".
The investigation is still active but has not yet concluded.
The bakery and takeaway outlet was gutted in a fire on December 28, just two days after Fitzies Bakery and Cafe owner Ray Jaggard had taken ownership of it.
It had been closed since before Christmas.
By the time two fire trucks arrived at the scene about 3am, the building was well alight, windows had blown out and there had been a few small explosions inside.
