In part nine of this series on home security, I am going to giver you a list of things to watch out for to help in spotting possibly suspicious people, its surprising how regularly we miss rather obvious signs that should put us on our guard.

1. Somebody going from house to house, this is particularly suspicious if, once a few homes have been visited, one or more of the people go into a back or side yard. It is even more suspicious if another remains in the front when this occurs. It may be that they are looking for a house to burglarize, or there could be a burglary in progress.

2. If somebody is waiting around in front of a home this becomes very suspicious if you know the homeowners are away. The individual you can see may be a lookout for a burglary that is in progress inside.

3. Everyone seen forcing an entry into a home. This is clearly suspicious at anytime and in any circumstances immediately dial 911 or 999 if in the U.K.

4. If you see anybody who does not live in the home, going into the yard, it is possible that a burglary is being committed.

5. Someone running away particularly if something valuable is being carried, they may be leaving the scene of a crime.

6. If you see somebody showing strange mental or physical symptoms, they may be injured or under the influence of drugs or alcohol.

7. Anybody moving property may be considered suspicious in some circumstances. Perhaps if it is late at night or if the item is not wrapped, it is possible that the article has been stolen.

8. A large number of comings and goings from a particular house, this may not be suspicious, unless it occurs on a daily or very regular basis, especially during late or unusual hours when it could signify vice or drug related activities.

With all of the above situations you must use your common sense, in the majority of situations there is a perfectly innocent explanation for what you see but if you are not certain dial 911 or 999 in the U.K. and let the police investigate.
