Muhammad Muhi, about 20 years old, was arrested on October 20 and is being held captive in a youth detention centre in Nakhon Si Thammarat province. 

Muhi initially denied all accusations, but finally confessed to joining the bombing plot and setting a bomb at a market near Patong beach on Phuket island. 

Upon receiving the information, Deputy Chief of Thai Royal Police Sriwara Rangsipramanakul has led a working group to the southern region to conduct further investigation. 

Muhi is scheduled to be taken back to Phuket for the crime re-enactment. 

After the bomb attacks on August 11-12 which claimed four lives and injured dozens, Thai police issued a wanted list of 11 suspects and captured three so far.
