Mercado turned himself into police after an arrest warrant was issued.
Officers in MA are calling an 11-year-old boy "courageous" after he found illegal drugs in his dad's bag and called police. The boy told police he had also seen his father conducting a drug deal earlier.
That's when the boy called police and said: 'I think my dad sells drugs'.
A man was taken into custody this week after his son reported him to be in possession of a large quantity of drugs.
Police who responded to the call found close to $10,000 worth of drugs hidden in a suitcase belonging to Yamil Mercado.More news: Trump lands in Saudi Arabia

The father is facing drug trafficking and child endangerment charges.
Lawrence police said they went to the home on Wednesday and confiscated over 200-grams of heroin with fentanyl valued at $8,500.
"He's fearless and insightful enough to know that this is a unsafe drug".
"I commend this young man for being fearless enough to come forward and report that these risky substances were in his home", a police official told the news station. They won't be releasing the man's name or his photo at this time, they told Boston 25 News.
The boy is in the care of family members. The Department of Children and Families is also investigating.
