this is Shinichi Kudo:

 Shinichi is a fairly famous high school detective who frequently helps the Tokyo police solve murder mysteries.

One day, Shinichi brings his friend Ran to a local theme park called Tropical Land, to celebrate her victory in the Metropolitan Karate Championships. He later ends up solving a murder case there. As they are leaving, Shinichi heads off alone to follow a suspicious man in black, Vodka, who was a suspect in the earlier murder. Shinichi witnesses a blackmail exchange between Vodka and a company president in a secluded area just outside the park, but is too engrossed to notice Gin, Vodka's partner, sneak up from behind. Gin knocks him out and forces him to swallow a new experimental poison known as APTX 4869, and they then leave him to die. However, instead of killing Shinichi, a rare side-effect occurs: his body shrinks into that of his six year-old self.After escaping from well-meaning but skeptical park security, with nowhere else to go Shinichi heads home. He there runs into his next door neighbor and close family friend, Professor Agasa, who warns him that he must keep his identity secret because the Black Organization will kill him and others associated with him should they discover the truth.
