TAMARAC - A 4-year-old at a Tamarac preschool caused a furor when police say he pulled a plastic bag of pot from his book bag and casually told a classmate, "That's my brother's weed."

Authorities say the incident occurred Friday at Tamarac Preschool, at 6801 W. Commercial Blvd.

Teacher Iris Dasilva, 45, of Coral Springs, checked the child's bookbag and found two more small resealable bags filled with marijuana, according to the report.

Dasilva called the Broward Sheriff's Office and the child abuse hotline.

According to the Sheriff's Office, the preschooler initially told investigators his older brother, 21, hid the drug in the book bag. The boy later said he found it on a table in his brother's room, the report said.

The boy's mother, whose name was not released, told investigators she had never found marijuana in her house and that there was none in the bookbag when she packed it.

Neither Dasilva nor the preschool's director could be reached this morning.

The event sparked a policy change at the preschool: A sign on the front door on Wednesday said, "We no longer allow backpacks or bookbags."

A Sheriff's Office deputy and an investigator for the Department of Children and Family Services conducted a visit to the child's home and found it clean, in order, with plenty of food, the police report said. The investigation is continuing.

The marijuana was scheduled to be destroyed, the report said.
