Four local police departments received suspicious deliveries Friday.
Mid-afternoon Berkeley police partially evacuated their headquarters after a suspicious package was reported there.
That came not long after an unknown substance was reported in the San Leandro Police Department's building, authorities said.
A hazardous materials team and firefighters arrived at the San Leandro police station at 901 E. 14th St. around 1:45 p.m., Alameda County fire spokeswoman Aisha Knowles said.
In Berkeley, a suspicious package was then reported in the building at 2100 Martin Luther King Jr. Way at 2:15 p.m., Berkeley police said.
Knowles did not know if the San Leandro and Berkeley incidents were connected to a report this morning of a powdery substance delivered to the Hayward Police Department.
Tests this afternoon revealed the substance in Hayward was not anthrax, according to Hayward fire officials.
Then, at 3:05 pm, the Union City Police Department became the fourth local office to report the delivery of a mysterious substance.
Alameda County's hazardous materials team responded to the Union City Police Department in the 34000 block of Niles-Alvarado Road, county fire spokeswoman Knowles said.
The police departments are now working together to see if the incidents are related.
