Where was John Surratt on April 14, 1865 ?

What led the Metro Police to the Surratt home so quickly after the shooting? It is my understanding that John Surratt's name started circling 45 minutes after the attack as the attacker of Seward. I understand that Surratt and Booth were known acquaintances but Booth was a famous man who had many acquaintances.

What specific tip had they received that led them there so quickly? I can't imagine that it was from questioning of those at the theatre that could have had that quick of a reaction.

From wiki: "Department of War employee Daniel Gleason, had alerted federal authorities to Confederate activity centered on the Surratt house, but this does not explain why D.C. police rather than federal agents appeared there."
