Aimed gun at son's head
It was on October 10 last year that the incident occurred.
The robbers pointed a gun at both the father and the son's head.
When the father also told them that he did not have the payment for the electric bike with him, the robbers tried to tear the four-year-old child from his arms.
The robbers, however, came across the father's activity watch and mobile phone.
