Honolulu police bomb specialists are not seeing an increase in the number of incidents involving suspicious devices or unattended property in recent weeks, although there have been several high-profile cases since the April 15 bombings in Boston, the head of the HPD bomb unit said Friday.

Maj. Alexander Ahlo, commander of HPD’s Specialized Services Division, reiterated that his staff takes all such threats seriously, and he urged the public to be vigilant in the wake of the Boston tragedy.
