The army was called to Upper Mount Gravatt after a man renovating the post-war house on Lay Street discovered three World War II grenades in a box under the hot water system.

The historic find included a World War II-era Italian Red Devil grenade and Mk2 or ‘‘pineapple’’ grenade.

Senior Sergeant Craig Smith said the home owner called police about 1pm.

Police cordoned off the scene, while an army bomb disposal team from Brisbane’s Enoggera Barracks removed the three devices.

‘‘The grenades were found to be inert, but no one would have known that,’’ Senior Sergeant Smith said.

The street was declared safe about 3pm.

“The home owner certainly did the right thing,” Senior Sergeant Smith said.

“These things can be very fragile, depending on age, and you just don’t know how unstable they might be. In fact, they can be more dangerous than they were when they were first made.

“We encourage any member of the public who might find old devices like this to leave them in place and call police. You would rather err on the side of caution with these things.”

Senior Sergeant Smith said police had been called to at least two other post-war homes in the area, where bombs or grenades had been found by unsuspecting renovators in the past.

The suburbs of Mount Gravatt and Holland Park, particularly around Marshall and Seville roads, were established as post-war settlement areas for returning diggers and their families.

‘‘There are a lot of war service homes through here,’’ Senior Sergeant Smith said.

‘‘The diggers came home and obviously brought souvenirs with them. They have either passed away or moved on and left the bombs or grenades behind to be found by the new home owners.’’
