PLANO -- A second school in Plano Independent School District received a letter containing a mysterious powder.
Bogess Elementary School received a letter on Tuesday morning.
School officials reportedly received an unidentified envelope on campus, but officials did not open the letter.
Reports of similar packages delivered to schools in Texas and three other states on Monday prompted school officials to follow important procedures. The envelope was placed in a sealed bag and stored in an area away from students until the Murphy Police and Fire Departments arrived.
Test showed nothing harmful was in the sealed envelope and posed no threat to students.
The FBI is conducting an investigation.
Parents will receive a letter today informing them of the letter containing white powder.
A mysterious powder was found at four North Texas schools and one business on Monday. Gulledge Elementary in Plano, Don Whitt Elementary and Wylie High School in Wylie ISD, and Sunset High School in Dallas all received letters. In those cases the powder was corn starch.
