"Don't become robbers like us. Study hard, become doctors and lawyers and make your parents proud," they told six primary schoolchildren present during the robbery.
The robbers had entered the house in Taman Batang Melaka at about 9pm and held up tuition teacher M. Sashi, 35, who was giving lessons to six primary schoolchildren aged between eight and 11.
They tied him, his wife and elderly mother before forcing the children to lie face down and remain silent.
One of the pupils' uncle, who came to fetch his 10 year-old nephew, was also held and tied up.
Sashi said the robbers had also asked his mother for forgiveness.
"Don't think too harshly of us. We too are like your son trying to make a living. Forgive us," he said.
Jasin CID chief Asst Supt Ahzarha Abdul Rahim said the robbers, believed to be in their 20's, stole an estimated RM150,000 worth of jewellery, an LCD television set and RM1,500.
"We believe the robbers may have known the victims or were working for someone who knew them," he said.
He urged those with information to contact him at 012-632 0050 - The Star
