Bangkok Metropolitan Police deputy commander Pol Maj Gen Anuchai Lekbumrung, who leads the investigation, said Malaysian authorities requested more documents related to the bombings and investigation, which police would forward soon.
Anuchai said the legal procedures against Sedaghatzadeh should not be complicated as Thai authorities had received solid co-operation from Malaysia. He could not say when Thai police would take custody of Sedaghatzadeh.
The Iranian fled to Malaysia on the day of the bombings but was arrested by authorities at Kuala Lumpur International Airport.
