County police are investigating the death of a 4-month-old girl whose father called 911 for help, saying she had stopped breathing, authorities reported.

When paramedics arrived at the Pasadena home in the 1100 block of Annis Squam Harbour about 1: 30 p.m. yesterday, they found the father attempting to revive the infant with cardiopulmonary resuscitation, said Sgt. William Krampf, an Anne Arundel County police spokesman.

Krampf said the paramedics continued CPR until arriving at North Arundel Hospital, where the infant was pronounced dead.

The names of the infant and father were not divulged last night while the investigation continued, Krampf said, adding that an autopsy was to be performed today.
