A kindergarten teacher inadvertently called police to the scene of a $1 million armed robbery yesterday when she reported an unrelated crime.
Police were called to the Bambino English Playschool after the teacher heard a 'bang' and found bullet holes in a school window at about 2.20 pm.
However, firearms experts said the shots were not fired by gun-wielding robbers who raided the Golden Golden Shop below the school and fled with jewels worth $1 million at the same time.
The robbers calmly carried out the raid in Causeway Road, Causeway Bay, without firing a shot. A separate investigation has been launched to determine the origin of the bullet holes.
Two saleswomen were bound and gagged by the two robbers, who showed their semi-automatic guns to shocked staff without saying a word.
'They didn't declare robbery. They just showed the shopgirls the guns and pushed two of them into the office at the back, tied them up and gagged them,' said Senior Inspector Jessie Wong Tze-yim, of the Happy Valley Crime Squad.
The third staff member was told to grab all jewellery from the shop's display cabinets.
No customers entered the store throughout the ordeal.
Within five minutes the robbers had also removed the tape from a closed-circuit television security system and fled.
Mr Wong said police called to the kindergarten arrived at about the same time that shocked staff reported the robbery.
'Our ballistics experts say the holes were not from pistol bullets, but probably from air rifles,' said Inspector Wong.
'No one else heard the shots.' Police said the robbers both wore light shirts and dark trousers. One had a fat build and the other was thin.
Both are thought to be aged between 20 and 30 years.
