Danbury Police are offering some advice for Black Friday to protect shoppers while out and about tonight and tomorrow.  One of their primary recommendations is to keep parked vehicles locked and remove all items of value, partly because there's been an uptick in thefts from vehicles in the past year.  Police say shoppers should keep at least one hand free at all times and not to carry so many bags that you become an easy target for someone who may want to assault or rob you.  Police also recommend shopping during daylight hours, when possible, and if you must shop at night to go with other people.  If you see someone who looks suspicious in the parking lot, police recommend not parking by that person and informing security or Police of their presence.
