Ghaziabad Senior Superintendent of Police K.S. Emmanuel said the two -- identified as Abhisekh, 22, and Gaurav, 20 -- admitted to their crime.
Emmanuel said Abhishek had studied for the Bachelor of Business Administration (BBA) course from IMS Ghaziabad while Gaurav was a matriculate.
Abhishek, along with another accused Pahalwan, carried a bag containing an AK-47 and four pistols, which he dumped in his three-wheeler after the attack, and escaped.
The other accused who were in another vehicle with Gaurav, were being tracked, the official said.
The Uttar Pradesh Police had on Wednesday announced it had solved the case following the arrest of four shooters involved in the shooting.
Police said the four shooters were hired by two cousins from Teotia's native village to avenge a family member's killing 17 years ago.
Inspector General of Police Meerut Zone Sujeet Pandey told the media here that main conspirators Manish and Manoj, both cousins, hailed from Teotia's native village Mahrauli under Kavi Nagar Police Station of Ghaziabad.
Both had hatched the conspiracy to avenge the murder of Manish's father Suresh Diwan, a Delhi Police Constable killed in 1999 in Shakarpur in Delhi.
