WASHINGTON (AP) -- Washington police stepped up security today following the arrest of seven World Bank protesters and confiscation of equipment they allegedly planned to use for blockades.
Police made the arrests Wednesday night after stopping two vehicles filed with ''lock boxes,'' lengths of PVC pipes that demonstrators can use to lock arms and make it difficult to break a ''human chain.''
The seven were charged with possession of implements of crime.
An increased police presence -- even for security-conscious Washington -- was evident on bridges spanning the Potomac River, at downtown street corners and near office buildings, particularly in blocks surrounding the World Bank headquarters.
