The total number of crimes in the Penn Patrol Zone in January 2009 is the same as this month in 2008.

Although the total number stayed fixed at 60, crimes against people increased from five to eight and crimes against property decreased from 55 to 52, according to the Division of Public Safety.

The number of robberies and the number of forcible sex offenses remained constant from last year to this year at three and one, respectively.

Burglaries doubled from three last year to six this year.

Bike thefts decreased a significant 75 percent, going from four last year to only one this year.

The decrease in bike thefts is a result of more students using U-locks to secure their bikes, according to Undergraduate Assembly member and College sophomore Alec Webley.

"Bicycles should be secured using a high grade U-lock at all times," according to the DPS Web site. "Cable locks are easily defeated and are ineffective in deterring theft."

DPS spokeswoman Stef Cella credited the UA with helping to promote better bike protection.

Webley said the decrease in bike thefts shows the success of Operation Theft Awareness, a collaborative educational campaign to reduce theft of unattended property.

"We've been working with local retailers to stop selling cable locks," he said.

Last week, the UA also passed the Bike Safety Proposal, an initiative to transform Penn into a more bike-friendly campus.
