Police were searching for two robbers who broke into a Palolo grandmother’s home Friday afternoon and tied her up before robbing her.

The grandmother, 65, was home with her 2-year-old granddaughter when the unknown males entered her home at about 1:40 p.m.

When the males were confronted, they assaulted and bound the grandmother, then took items before fleeing.

One of the males brandished a handgun, police said. Police said the grandmother did not know the males and the robbery appeared to be random.

Police opened a first-degree robbery investigation.
