Perth detectives are investigating the alleged ignition and detonation of an improvised explosive device and the seizure of a second similar device yesterday.
“The explosion caused shrapnel and debris to cover a distance of about 10m,” police said in a statement.
“No one was injured in the incident and the item appeared to be a homemade, makeshift device that had been ignited.
“The remnants of the device were seized by police for forensic examination.”
Police said they were then called to a location near the intersection of Wellington Street and King Street in the Perth CBD at about 10.20pm yesterday after a person reported they were in possession of a similar improvised explosive device.
Officers were told they had taken the device from a vehicle belonging to a person known to them.
Police and emergency services attended the scene and “cordoned off the area to keep the public safe”.
“TRG Bomb Response Unit officers attended and rendered the item safe,” police said.
“The item was confirmed to be a homemade, makeshift device similar to the one detonated in Leederville earlier in the day.”
As a result of investigations, Perth detectives visited a home in Lansing Street in Queens Park in the early hours of this morning and executed a search warrant.
A 29-year-old man was taken into custody without incident and is assisting detectives with the investigation.
