A man identified as Ali Mahmud, 23, reportedly robbed his own grandmother on Tuesday morning in Bekasi, West Java and beat her in the head and face with bricks.
East Bekasi police head Comr. Parjana said the alleged perpetrator pretended to be a guest and knocked on the door of his grandmother's house. When the door was opened, Ali reportedly struck the woman's head with bricks.
"He took Rp 3 million (S$300) and 10 grams of gold jewelry," Parjana said, as quoted by wartakota.tribunnews.com.
The grandmother's maid, Nurhasanih, 30, found her and asked for help from the neighbours to take her to the hospital.
Currently, the police are still trying to catch Ali who fled outside the city.
The police's criminal unit head First Insp. Yusron said the grandmother was recovering even though she was still wounded.
"We have deployed our officers to capture the [alleged] perpetrator. We encourage him to surrender," Yusron said.
As evidence, the police seized a long piece of cloth, one brick and four brickbats used to beat the victim. If found guilty, Ali could face a maximum of nine years' imprisonment, the police said.
