Cash was taken in a daylight robbery on a security van,
Two men in balaclavas approached a security guard carrying a cash box outside Morrisons in Park Road, Ormskirk at around 2pm yesterday.
They told the security guard to drop the box before taking making off with the cash.
It is believed the two offenders then sped away in a black BMW convertible, which was waiting for them in Aughton Street.
The driver of the vehicle was described as a stocky, white man. The black box was later found smashed in Black Moss Lane.
Police will now be monitoring local laundrettes in case anyone tries to launder the money.
DI Jane Webb, from Lancashire Police, said: “We know that the offenders are likely to have activated the dye mechanism on the cashbox.
“I would urge anybody who has witnessed this incident or anyone who appears to have indigo blue dye or ink marks on their clothing or body to contact the police.
“Similarly, I would appeal to anyone who saw the Black BMW or who has any information that could assist with our investigation to get in contact with us.”
