According to Kuala Lumpur Police Chief Amar Singh, Bank Simpanan Nasional (BSN) staff had informed police at 5am today on what they thought was a hand grenade near a cash deposit machine at the bank in Taman Midah.
Amar said a bomb disposal unit (UPB) swept the area and found a toy that resembled a hand grenade.
He added that a full sweep was conducted of the area, which included combing through closed circuit television (CCTV) footage.
The toy was then sent to the police forensics unit for further investigations.
Malaysia has faced several threats from IS in recent months, with one incident reported at the Movida nightclub in Puchong. A hand grenade was thrown at the outlet, injuring eight people watching a late-night football match.
Inspector-General of Police Khalid Abu Bakar confirmed that it was an act of terror by terror group Islamic State (IS).
Police have named Muhammad Wanndy as the man who gave orders to carry out the June 28 attack.
Police said this was the terrorist’s personal way of avenging his elder brother, Mohamed Danny, who was charged in a Malacca court last month for channelling funds to the militant group.
