Delhi Police — Accident Case 25th Dec not yet registered

Dear Sir,

I m resident of kalkaji Extn south delhi, there was an accident occured with my brother where we called the police on spot and hold the accused till police came and handed over him and his bike at Govind puri police station. But it is so strange that police has not yet registered the FIR. My borther has admitted to AIIMS trauma centre and MLC was created but police has not taken any action on it. Investigation office name is Ramavtar, [protected] his no. Plz provide the reason why accused was released without our consent or information. And what police is doing from last 7-8 days on my case.
