Alleged bank robber flees, tries to hide — in another bank

An man allegedly robbed a bank this morning in Littleton, then fled across the street and tried to hide — in another bank, police said.

Christopher Grannis, 25, of Littleton was arrested just before noon today and charged with bank robbery, assault, and intimidating a witness, said Littleton Deputy Police Chief Matthew J. King.

Grannis allegedly passed a note to a teller, who then handed him an undetermined amount of cash at the Northern Bank and Trust at 11:20 a.m., King said.

Grannis then fled across the street to Citizens Bank, where he was arrested by Littleton police five minutes later.

“The people in the [Citizens Bank] bank had a little surprise when members of the police department burst in there,” King said.

When officers brought Grannis back to the Northern Bank and Trust on Great Street to see if witnesses could identify him, Grannis allegedly saw the teller to whom he passed the note, “and told her he’d kill her,” King said.

Littleton police had had minor contact with Grannis previously, but “nothing serious,” King said.

Grannis will be arraigned at Ayer District Court later today.
