in Hallowe'en activities.

They warned such people would be dealt with "to the full extent of the law as warranted''.

The move is part of a three-pronged offensive against Hallowe'en trouble-makers.

Off-duty officers, backed by the Reserve Force, will also beef up Police patrols over Hallowe'en.

And uniformed Police patrols on the streets -- and in cars -- will be increased.

The initiatives were put together by Police Commissioner Colin Coxall and Acting Assistant Commissioner Vic Richmond.

"Unfortunately such measures have become necessary in light of the deterioration of what was meant to be night of harmless fun for children in particular,'' said Police spokeswoman Evelyn James Barnett.

"Because of the selfish and irresponsible actions of groups of youths behaving in a threatening manner to members of the community, including young children, we deem it necessary to become involved in this manner to ensure the overall safety of the public.

"These measures will be reviewed each year on an ad hoc basis.'' Ms James Barnett said the behaviour by some members of the public last year was "totally unacceptable''.

Seven people were arrested last year, including a juvenile, for such offences as possession of offensive weapons, throwing a firebomb at Police, assault and theft.

"Again such behaviour will not be tolerated this year,'' added Ms James Barnett.

Two private schools, Bermuda Institute and Warwick Academy, have announced plans to close early this year on Hallowe'en.

Last week, Warwick Academy students were reportedly targeted by a busload of egg-throwing Warwick Secondary youngsters.
