Lawrence Mayor William Lantigua says it is too early to say whether he will ask for a recount after unofficial election results showed a narrow victory for challenger Daniel Rivera.

Lantigua's attorney said Wednesday at a news conference with the mayor they would wait until provisional and absentee ballots were tabulated before considering his next move. Under state law he has up to 10 days to request a recount.

Secretary of State William Galvin, the state's top elections official, says ballots from Tuesday's election have been locked in a vault under police guard in anticipation of a possible recount.

Rivera, a city councilor, claimed victory after an unofficial vote count showed him ahead by 60 votes.

Rivera said his campaign fought for every vote and will make sure "this election does not get stolen."
