LONDON (Reuters) - London s East Croydon station was due to reopen on Monday after police said an item they had been investigating was not harmful.  The item at East Croydon has been declared non-suspicious,  Britain s transport police said on Twitter.  The station will be reopening very shortly.  The temporary closure caused delays for commuters and for travellers using the city s nearby Gatwick Airport.
