JAKARTA, Indonesia – Bomb-making materials were found at a house in Jakarta and police are investigating links to terrorism, local media reported.

Jakarta police spokesman Colonel Rikwanto said Thursday (September 6th) that residents rushed to Muhammad Toriq's home after thick plumes of what appeared to be smoke shot up from the house late Wednesday.

It turned out it was a cloud of white explosives material, accidentally knocked over inside the house. Witnesses say Toriq, 32, covered in the powder, ran past them and escaped, leaving his wife, mother and children inside.

Rikwanto said that he would be co-ordinating efforts with the anti-terrorist police squad Detachment 88, as among the materials found inside were detonators, aluminium powder and sulphur.

He said the explosives were packed with ball bearings and nails to maximise the impact of potential blasts.
