Two Jericho schools remained on lockdown for the second straight day Tuesday after high school students received text messages that included a bomb threat, the district superintendent said.

Superintendent Henry L. Grishman said the high school and middle school remained on lockdown and said a decision would be made Tuesday evening on whether to continue that status Wednesday.

A Nassau police spokeswoman said the Jericho situation remains "an active investigation" and said the school district is "erring on the side of caution" because of the threats made in the text messages.

Grishman said police have had a presence at the school campus since officials were alerted to the situation on Sunday. Grishman also said the situation has not affected voting Tuesday, with polls open at the schools from 6 a.m.-9 p.m.

"We swept the school Sunday," Grishman said. "We've been under tight security since then . . . Heightened security is basically what is taking place."

Grishman said only four entrances to the schools are being used and said all are manned by security personnel.

All bags are being searched, Grishman said.

Grishman also said all extracurricular activities at the middle school and high school, which share the campus, will go on as scheduled Tuesday.
