A 22-year-old man was detained on Thursday night and later released on bail pending further police enquiries.
He was held after two women, aged 21 and 23, and a 19-year-old man were arrested.
They were also bailed to return at a later date.
The four were questioned in connection with the blaze at the Colin Centre at Pembroke Loop Road in the Poleglass area.
Four shops, including a supermarket and a chip shop, were gutted in the fire which was reported at around 4am on Tuesday.
The business premises employed at least 30 people in the area.
