The police offered these tips to local businesses to help prevent robbery:

• Have at least two employees open and close the business.

• Install a burglar alarm.

• Place a surveillance camera behind the cash register facing the front counter with a digital recorder.

• Vary times and routes of travel for bank deposits.

• Keep a low balance in the cash register. Don't leave large bills under the drawer.

• Place excess money in a safe or deposit it as soon as possible.

• Stay alert. Know who is in the business and where they are.

• If you see something suspicious, call the police. Never try to handle it yourself.

• Use care after dark. Be cautious when cleaning the parking lot, taking out the trash, or going to your car after work.

• Make sure to post important signs: "Clerk cannot open the time lock safe" or "Premises protected 24 hours by video surveillance."

• Cooperate with the robber for your own safety and the safety of others. Comply with a robber's demands. Remain calm and think clearly. Make mental notes of the robber's physical description and unique characteristics.
