Another Police procedure question. If somebody was seen fleeing the scene of a crime (not by Police...)?

If the person who witnessed the person who was running away knew their name or something about them sufficient to identify them and gave that information to the police then yes perhaps they would be arrested as a suspect. Otherwise, no as no-one would be able to identify them. If a police dog was bought to the scene in suffient time with the correct conditions, not icy or pouring with rain, the dog could possibly follow the scent. ( the weather affects their ability to pick up the scent in the very cold and the rain dilutes the scent.)

I think the police would arrest straight away if sufficient evidence to identify. After that, they would be able to match forensic evidence at the scene with the suspect.

I would suggest by your question, that if someone was seen to flee the scene of a crime, he must be for the time being a "suspect".If at a stage this person can be identified he could be arrested on suspicion by the police and questioned under caution.Depending on the interview and on the fact as to whether any evidence could tie down this person to the crime, he would be charged with that crime.

If however no such evidence is forth coming he or she will be free to go about their business.

If the police suspected them of the crime they would be taken in for questioning under caution and later arrested if the police thought they had enough evidence to push for a conviction,they would be bailed if the crime allowed it,if the police have nothing on this person other than a suspicion then they may take them back in for further questioning at a later date,

They would not be arrested because there as yet wouldn't be probable cause, but the police might try to locate them as a possible witness.

Seems like there's a lot of book writers that come on here everyday.

If he witnessed the crime he could desire to definitely arrest him. in the event that they understand one yet another he could % to call yet another officer to make the arrestto dodge conflict of pastime matters. If he fails to document the crime or make the arrest, then he's likewise commiting against the regulation. And it may basically be grand robbery if it replaced into over a undeniable quantity. If it replaced right into a $4 hundred bracelet, in some places that may no longer even an arrestable offense.

the police could not do anything but ask questions, for their is no reason for the subject to be placed under arrested, you say you are writing a book, it is sad that you don't even know your rights as a citizen, this is why comes think they can do anything
