In an attempt to prove his crime-fighting skills to the force, Haracharan outlined his many talents, which included excellent hand-eye co-ordination as well as healthy amounts of "stealth".
"I am good at dodging objects and I got good eye sight," he wrote.
"I am good at jumping from high places and I got lots of stealth."
He explained to be an effective police officer, candidates must have "lots of focus and eye sight" — qualities which he excelled at.
"To be a good police officer you need to check stuff," he continued.
"I am good at guarding places."
Haracharan concluded he would be a perfect crime fighter "because I am good at climbing".
Posting the "wonderful letter" to their Facebook page, the Cambridge City Police explained Haracharan wrote the letter as part of an exercise on "persuasive letters."
"We are definitely persuaded!" the post said.
The post also explained, while certainly appreciated, "jumping from high places is not strictly necessary" for future police academy candidates.
Haracharan may have to wait a few more years before he can suit up for a routine patrol, but that didn't stop the public applauding his determination.
"Hope you've signed him up!" one woman wrote.
Another said the little boy was "so cute".
"Bless him! I wonder if he will change his mind when he grows up," a third wrote.
Officers from the school also visited Haracharan's school this month, which his teacher thanked them for.
"Thank you so much for taking the time out to visit us in school," the teacher said.
"It was such a memorable experience for the children and has helped show writing has a purpose and an audience."
