(CNN) A Massachusetts man pleaded not guilty Friday to drug possession and reckless child endangerment charges after his 5-year-old son brought cocaine to school.

Holyoke police said the boy ingested the cocaine, was taken to a hospital and is expected to be OK, according to CNN affiliate WGGB-TV . Benny Garcia, 29, the child's father, is being held without bail until a dangerousness hearing on Wednesday to determine whether he will continue being held pending a trial.

CNN has reached out to Garcia's lawyers but has not heard back.

The kindergartner at H.B. Lawrence Elementary School last week was showing his friends a drug-filled plastic baggie stamped with his favorite superheroes, according to a letter from the school principal, Catherine Hourihan, to parents.

"The kindergarten student told the teacher that when he eats or tastes the powder, he turns into Superman," said Matthew Green, Hampden County assistant district attorney, in court video from WGGB.
